Three novel coordination polymers of EuIII trifluoroacetates with imidazo-tetrazine bioactive derivatives of composition [Eu(OOCCF3)3 L]n (L1=3-(3,5-dimethylpyrazole-1-yl)-6-(isopropylthio)imidazo[1,2-b][1,2,4,5]tetrazine (1), L2=3-(3,5-dimethylpyrazole-1-yl)-6-(phenylthio)imidazo[1,2-b][1,2,4,5]tetrazine (2), L3=3-(3,5-dimethylpyrazole-1-yl)-6-(benzylthio)imidazo[1,2-b][1,2,4,5]tetrazine (3)) have been synthesized and fully characterized. According X-ray data, the polymer structure of 1–3 is provided by the crosslinking of europium atoms by bridging trifluoroacetate anions. Each europium atom additionally coordinates the imidazo-tetrazine ligands by chelated mode. The obtained coordination polymers are highly soluble in organic solvents, and also possess the lipophilicity necessary to ensure biological activity. UV spectroscopic data indicate that ligand coordination is preserved upon dissolution in physiological saline. The study of antibacterial properties of polymers showed high activity of complexes in vitro against reference strain Mycobacterium tuberculosis H37Rv.
New diorganotin(IV) complexes R2Sn(Ln) 1-5 (where R = Et, t-Bu, Ph) with O,N,S-donor tridentate Schiff bases containing chlorine or trifluoromethyl groups were synthesized in 49-67% yields. Compounds 1-5 were characterized by 1H, 13C NMR, IR spectroscopy, and elemental analysis. The molecular structures of 2, 3, and 5in the crystalline state were determined by single-crystal X-ray diffraction. The organotin complexes are mononuclear and five-coordinate, with ligands adopting a dianionic form. Electrochemical studies revealed that the electrooxidation process is irreversible while the electrochemical reduction generates relatively stable monoanionic complexes. Complex 3, along with previously reported related phenyl-or ethyl-substituted tin compounds, exhibits luminescence in chloroform. The radical scavenging activity of the complexes was evaluated in reactions with ABTS radical cation or superoxide radical anion in NBT assay. The highest neutralizing properties were observed for complexes with ethyl substituents at tin atom; their IC50 values ranged from 6 to 35 mu M. In the oxidative DNA damage assays, most compounds exhibited a promoting effect suggesting their potential role in DNA cleavage under oxidative stress. However, in the lipid peroxidation model reaction in vitro, an antioxidant effect was observed for most compounds, particularly for hydrophobic tert-butyl-containing complexes 2 and 4.
Silver complexes are potential antimicrobial agents that trigger destructive processes in bacterial cells, leading to their death. Their ability to simultaneously stimulate tissue regenerative properties also makes them promising components in the development of medical materials. A common complication arising from the treatment of bone tissue damage is hospital-acquired infection, requiring repeated revision surgeries. The use of bone grafts with antibacterial properties can help solve this problem. New pyridine complexes of silver(I) with thiophenecarboxylic (Htph) and nitric acid anions have been synthesized: [Ag(tph)(py)2]n·nHtph (1, py-pyridine) and [Ag(bpy)]n·nNO3 (2, bpy-4,4'-bipyridine), the structures of which have been determined using X-ray analysis. Despite the fact that 2 is a known structure, we were able to obtain new cell parameters by conducting an X-ray diffraction analysis at a lower temperature of 100 K. According to X-ray diffraction data, both compounds are polymers in which the cationic part is formed by linear fragments (CNAg = 2) [Ag(py)2]+ (1)/[Ag(bpy)2]+ (2), and acid anions act as counterions. The presence of intermolecular and non-valent π-π interactions provides additional stabilization of supramolecular levels. Aqueous solutions 1 and 2 are stable for two weeks, according to UV-Vis data. Incubation of crosslinked resorbable polymer matrices functionalized separately with complex 1 or 2 in saline solution revealed a sustained, prolonged release of silver ions over 14 days. Evaluation of the antimicrobial potential of 1 and 2 against Gram-positive/Gram-negative species and fungi demonstrated moderate, controlled bacteriostatic growth inhibition broadly across tested strains, confirming the bifunctionality of the crosslinked hybrid matrix systems-moderate suppression of bacterial growth while simultaneously stimulating tissue regeneration. An increase in cell viability, expressed in their active proliferation under the influence of complexes 1 and 2 up to 156%, as well as calcium deposition, indicates the high cytocompatibility and pro-mineralization capacity of the new compounds.
The design of salicylhydroximate metallacrowns has attracted increasing attention over the years due to their unique structure and possible biological activity. Here, we demonstrate the differences in the conformation of metallamacrocycles based on salicylhydroxamic acid and its 5-substituted (Cl-, Br-, I-, and NO2-) derivatives. The geometric characteristics of intermolecular halogen and hydrogen bonds were investigated. Hirshfeld analysis of intermolecular interactions that have a crucial role in the 3D structure of these complexes was conducted. In all five complexes, the most significant interactions involve H…O, H…H, and H…C contacts, but the regions of the shortest intermolecular interactions vary significantly depending on the substituent. Electron density analysis revealing substituent influence was performed both for the salicylhydroxamic acids and the corresponding metallamacrocycles on the basis of DFT calculations. Metallamacrocyclic complexes based on the salicylhydroxamic acid and Cl- and Br-substituted acids do not exhibit biological activity relative to Mycolicibacterium smegmatis, a model for Mycobacterium tuberculosis (M. tuberculosis). In contrast, the complexes bearing the I- and NO2- groups act bacteriostatically against M. smegmatis strain. However, they completely lose antibacterial activity towards M. smegmatis strain over time.
Lanthanide complexes, due to their photophysical and biological properties, are interesting as luminescent probes in bioimaging. A series of new thiophencarboxylate (tph) trivalent lanthanide complexes of the composition [Ln2(tph)4(OAc)2(phen)2] (LnIII= Gd (1), Eu (2), Sm (3), Tb (4)) was synthesized by the reaction of incomplete ion exchange of the corresponding lanthanide acetates with thiophencarboxylic acid and subsequent addition of 1,10-phenanthroline (phen). The resulting compounds were characterized using single crystal X-ray diffraction, FTIR spectroscopy, and elemental analysis. According to the X-ray data, compounds 1-4 are isostructural binuclear heterocarboxylate bridged complexes. The photo physical analysis of complexes 1-4 showed intense lanthanide-centered luminescence due to ligand excitation. The PLQY of complex 2 is 30%. The cytotoxicity of the complexes was tested in vitro against SKOV3, HCT116, A549, SKBR3 cancer cells and non-tumor culture of human dermal fibroblasts (HDF). The europium complex 2 demonstrated activity against ovarian adenocarcinoma (SKOV3) with an IC50 of 2.7 and a selectivity index of 3. Stability of the aqueous solutions of the complexes was confirmed by UV-vis spectroscopy. DNA binding of complexes was investigated by electronic absorption spectroscopy and low-gradient viscometry measurements. Detailed analysis revealed that these complexes interacted with DNA through intercalation binding.
A new supramolecular complex consisting of a β-alaninehydroximate metallamacrocyclic cation and a metal-organic cuprate anion was obtained and characterized using X-ray diffraction analysis and DFT calculations. The unique 3D supramolecular assembly is formed due to the system of Cu···O and Cu···N intermolecular interactions. The cuprate structure indicates delocalization of the electron density in the pyridinone-isonicotinamide fragment, which may contribute to the detected enhanced antimycobacterial activity of the complex.
Obtaining water-soluble palladium complexes capable of interacting with DNA is an important synthetic task in medicinal chemistry. The interaction of [Pd(phen)(OAc)2] (phen = 1,10-phenanthroline) with pivalic acid (tBuCOOH) and trifluoromethanesulfonic acid (HOTf) leads to the formation of the molecular complex [Pd(phen)(OOCtBu)2] (1) and the ionic complex [Pd(phen)(H2O)2]Otf2 (2), respectively. Complex 1 is highly soluble in water and stable in solution for 48 h. When complex 2 is boiled in water, it undergoes hydrolysis to form the binuclear hydroxo-bridged complex [Pd2(phen)2(μ-OH)2]Otf2 (3). According to X-ray diffraction data, the crystal lattices of 1–3 are stabilized by numerous intermolecular hydrogen bonds and π-π stacking interactions. The interaction of 1 and 2 with DNA in vitro (in 0.005 M NaCl solution) was studied using UV spectroscopy, low-gradient viscometry, and DNA melting analysis. It was shown that both compounds interact with DNA, and the binding is accompanied by the intercalation of the phenanthroline ligand at low concentrations in the DNA solution. An increase in their concentration leads to an alternative binding mode—palladium–DNA interaction causes a decrease in the DNA molecular coil size due to electrostatic interaction and/or palladium coordination to DNA bases. The difference between the binding of compounds 1 and 2 to DNA is that 2 can coordinate to N-bases, unlike complex 1. The antibacterial properties of the complexes have been studied in vitro against E. coli, P. aeruginosa, and S. aureus.
The creation of the "correct" surface in heterogeneous catalysis is an important condition for the optimal operation of a number of catalytic systems, for example, hydrogenation (nitrobenzene dicyclopentadiene). In this case, the interaction of the metal with the support plays a decisive role in the catalytic efficiency of the process. In the present work, a series of copper(II) complexes of the composition [Cu(fur)2(ampy)2]·L were synthesized, where fur- represents the anions 2Hfur (1 and 2) and 3Hfur (3 and 4); ampy = γ-aminopyridine (γ-ampy; 1 and 4) and α-aminopyridine (α-ampy; 2 and 3); and L = CH3CN (1). The crystalline products were isolated, and their structures were determined using the single-crystal X-ray diffraction method. According to X-ray data, it was established that the complexes with γ-ampy (1 and 4) are characterized by the formation of trans-isomers, whereas for α-ampy, the cis-configuration of the ligands is realized - the position of the amino groups in the α-ampy ligands is the main factor stabilizing the cis-structure of complexes 2 and 3. STA data of 1-4 revealed the volatility of trans-4, which has a smaller number of intermolecular hydrogen bonds, and quantum chemical calculations indicated high stability (-152.3 kcal mol-1). Crystallographic and geometric characteristics of trans-complexes 1 and 4 determined the formation of effective precatalytic surfaces (SEM data), allowing the hydrogenation of nitrobenzene (NB) and dicyclopentadiene (DCPD) to be carried out most efficiently under atmospheric pressure and low temperatures - the aniline yield was about 100%.
Five Ag(I) complexes with monocarboxylic acids, [Ag(Ind)(NH3)] (1, Ind-anion 2-indolcarboxilic acid), [Ag2(Myr)2(H2O)2] (2, Myr-anion myrtenic acid), [Ag2(PFBA)(Benz)]n(3, PFBA-anion 2,3,4,5,6-pentafluor-obenzoic acid, Benz-anion benzoic acid), [Ag2(4-ATFBA)2(CH3CN)]n(4, 4-ATFBA-anion 4-amino-2,3,5,6-tet-rafluorobenzoic acid), [{Ag7(nfur)8}{Ag(CH3CN)2}]n (5, nfur-anion 5-nitro-2-furoic acid) were synthesized. According to X-ray analysis Ag(I) is characterized by coordination numbers 2 (1), 3 (2), 4 (4 and 5), and is represented by the combination 3 + 4 (3). Complex 2 represents the first example of an aqua complex with a cisoid arrangement of carboxylate anions (bent conformation). The stability of the complexes was studied both in the crystalline state and in solution. The results of thermal experiments using the method of simultaneous thermal analysis (STA) 1 and 5 showed the stability of the complexes up to 170 degrees C. Solutions of all complexes remain stable to UV-vis spectroscopy at room temperature for 24 h, with compounds 1 and 4 also showing high stability for 14 days. For complexes 1-5, antibacterial activity against Mycolicibacterium smegmatis was assessed and the minimum inhibitory concentration values were comparable with the reference drug rifampicin (a first-line drug for tuberculosis treatment). Complexes 2-4 showed the highest biological activity (MIC 1-6 nmol/ disk), superior to rifampicin. Moreover, 2 (containing a natural ligand fragment of myrthenic acid) is characterized by bactericidal activity-the bacterial growth zone does not become overgrown over time. Molecular docking modeling revealed that complex 2 has a high affinity for several important M. smegmatis proteins. In particular, it has been established that the effect 2 on protein MSMEG_3151 (the target of anti-tuberculosis therapy) is similar to the effect of isoniazid, a first-line chemotherapeutic drug for tuberculosis treatment (Delta G-6.44 kcal/mol) due to extensive hydrophobic contacts, hydrogen bonds and electrostatic interactions. Antioxidant activity study 1 and 5 showed a slight decrease in ROS during oxidative stress.
New Yb(iii) coordination compound [YbT3(Bath)]& centerdot;0.5EtOH containing HT (HT = tropolone, 2-hydroxy-2,4,6-cycloheptatrien-1-one) and Bath (4,7-diphenyl-1,10-phenanthroline), was synthesized and identified based on Powder X-ray analysis data. The magnetic and photophysical properties of the obtained heteroleptic complex were studied and compared with previously acquired results for homoleptic dimeric complex [YbT3HT]2. The synthesized compound exhibits slow relaxation of magnetization under an external dc-field with a magnetization barrier of 38.2 K and demonstrates a higher luminescence quantum yield of 1.5%, compared to 0.9% for complex [YbT3HT]2.
The example of mixed-anion europium complexes containing pentafluorobenzoate (pfb), 1-naphthoate (1-nap) anions, with 1,10-phenanthroline (phen) or 2,2'-bipyridyl (2,2'-bpy) molecules demonstrates that varying the ratios of the starting reagents, as well as the conditions of synthesis and crystallization, allows for targeted control over the composition and structure of the resulting compounds: [Eu2(phen)2(1-nap)4(pfb)2]·2MeCN (1), [Eu2(H2O)2(phen)2(1-nap)2(pfb)4]·2MeCN (2), [Eu2(2,2'-bpy)2(1-nap)2(pfb)4]·2MeCN (3), [Eu2(2,2'-bpy)2(1-nap)3(pfb)3]·2MeCN (4), [Eu2(2,2'-bpy)2(1-nap)2(pfb)4]·2C6H6 (5), [Eu4(phen)4(1-nap)1(pfb)11]n·n[Eu2(phen)2(1-nap)2.7(pfb)3.3] (6), [Eu2(phen)2(pfb)6]n·2nMeCN (7·MeCN), [Eu2(phen)2(pfb)6]n·4nMeOH (7·MeOH). Furthermore, on the example of compound [Eu2(phen)2(1-NAA)2(pfb)4] (8), it was shown that mixed-anionic compounds can be obtained by combining the more flexible 1-naphthaleneacetate (1-NAA) and pfb anions. In compounds 3 and 6, some anion positions are disordered because both 1-nap and pfb anions occupy the same positions in varying ratios. The examples demonstrate that careful optimization of non-covalent interactions enables precise control over the structure and physicochemical properties of these coordination compounds, resulting in improved luminescent performance. The obtained compounds were characterized by single-crystal and powder X-ray diffraction, luminescence spectroscopy, infrared (IR) spectroscopy, and elemental (CHN) analysis. The photoluminescent properties were studied for the solid-state samples. Additionally, the density functional theory (DFT) method was employed to model the frontier molecular orbitals of the complexes and analyze their electronic structures.
The development of heterometallic complexes has emerged as a promising strategy in anticancer research due to their ability to act on multiple biological targets simultaneously. In this study, we report a novel synthetic approach to bi- and heterometallic palladium(II) complexes as potential anticancer agents. The reaction of [M(phen)(OOCtBu)2] (M = Zn, Cu, Pd) with the complex [Pd(phen)(MeCN)2](Otf)2 yielded three new water-soluble compounds: heteronuclear complex [PdZn(phen)2(μ-OOCtBu)2(H2O)](Otf)2 (PdZn), the first example of a heterometallic acetamidate-pivalate bridged complex [PdCu(phen)2(μ-OOCtBu)(μ-NHCOMe)(H2O)](Otf)2 (PdCu) and the homometallic complex [Pd2(phen)2(μ-OOCtBu)(μ-NHCOMe)](Otf)2 (PdPd). All complexes were fully characterized by single-crystal X-ray diffraction, IR, UV-vis spectroscopy, and mass spectrometry). The in vitro antiproliferative activity of the complexes was evaluated against HCT116 (colon), A549 (lung), and SKBR3 (breast) cancer cell lines, as well as normal human dermal fibroblasts (HDF). The complexes exhibited submicromolar IC50 values, significantly outperforming cisplatin. Notably, the complex PdPd demonstrated exceptional selectivity towards A549 lung cancer cells (SI = 29.3). DNA binding studies indicated a dual interaction mode involving both intercalation and minor groove binding. Molecular docking simulations suggest that the dissociated [Pd(phen)(NHCOMe)]+ fragment of PdPd act as a plausible pharmacophore, capable of binding to both DNA and the mutant KRAS protein, which is prevalent in A549 cells. The introduction of the heterometal into the complex leads to increased cytotoxicity toward HCT116 and healthy cells, suggesting an additional target of the heterometal fragment - in particular, ROS generation by PdCu. This study highlights the potential of designing palladium complexes that target multiple cellular pathways for enhanced anticancer efficacy.
To develop new approaches for the targeted synthesis of heterometallic compounds based on cyclobutane-1,1dicarboxylic acid (H2cbdc) anions, we studied the reactions of chromium(III) salts with Ba(cbdc) and 2,2 ' bipyridine (bpy) in water by varying the nature and ratios of the initial reagents. In all systems, we observed the formation of heteroleptic complex anions [Cr(cbdc)2(bpy)]- capable of acting as "building blocks" in the assembly of polynuclear architectures with Ba2+ ions. Partial hydrolysis of Cr3+-containing units in an aqueous medium was found to result in the formation of the homometallic binuclear complex [Cr2(OH)2(cbdc)2(bpy)2]& sdot; 6H2O (1). Further evaporation of the mother liquors, depending on the synthesis conditions, led to the crystallization of various types of compounds, i.e., the 2D polymer {[BaCr(cbdc)2(NO3)(bpy)2(H2O)]& sdot;H2O}n (2), the 1D polymers {[BaCr2(cbdc)4(bpy)2(H2O)5]& sdot;4.5H2O}n (3), {[BaCr2(cbdc)4(bpy)2(H2O)3]& sdot;4H2O}n (4), the 2D polymer {[BaCr(cbdc)2(NO3)(bpy)(H2O)3]& sdot;H2O}n (5), the ionic compound [Cr(cbdc)(bpy)(H2O)2][Cr (cbdc)2(bpy)]& sdot;4H2O (6), and the molecular compound {[BaCr2(cbdc)4(bpy)3(H2O)3]& sdot;7.25H2O}2 (7). Singlecrystal X-ray diffraction (SC-XRD) was used to determine the crystal structures of 1-7, and their phase purity was confirmed by powder X-ray diffraction (PXRD). The thermal decomposition of BaII-CrIII compounds 2, 4, 5, and 7 was studied using simultaneous thermal analysis (STA) in an argon atmosphere. The suitability of the resulting BaII-CrIII compounds as molecular precursors for complex oxides was demonstrated using compound 2 as an example. Its final solid-state thermolysis product obtained in air at 1100 degrees C was shown to be single-phase barium chromate (BaCrO4) in the form of particles ranging in size from 0.5 to 4 & micro;m.
The synthesis of a series of mononuclear Fe(III) and Co(III) complexes with N′-(3,5-di-tert-butyl-2-hydroxybenzylidene)-4-nitrobenzohydrazide (H2L) is presented in this article. The structure of all complexes was determined by single-crystal X-ray diffraction analysis. The confirmation of ligand’s coordination type in anionic or dianionic form and the distorted octahedral coordination environment is based on studies—using alternative methods, IR and UV–vis spectroscopy. A single-crystal-to-single-crystal phase transition was observed in the [FeIII(HL)2]2(ClO4)2·4MeOH complex. Evaluation of the biological activity of the complexes against the Gram-positive strain of Staphylococcus aureus and the Gram-negative strain of Escherichia coli showed a higher bactericidal activity compared with acylhydrazone.
It was established that the reaction of europium(III) or terbium(III) benzoate (bz-) with the corresponding 3,5-difluorobenzoate (dfb-) and 1,10-phenanthroline (phen) under different conditions leads to the formation of crystals of solid solutions [Ln2(phen)2(dfb)x(bz)6-x] (1Lnx, Ln = Eu (x = 0.6, 1.3, 1.6); Ln = Tb (x = 0.6)), [Eu2(phen)2(dfb)x(bz)6-x].2MeCN (2Eux, x = 2.0, 2.7), [Eu2(phen)2(dfb)x(bz)6-x].MeCN (3Eux, x = 4.45, 5.05), [Tb2(phen)2(dfb)2.5(bz)3.5].2MeOH (5Tb2.5) with various structures, as well as a hexanuclear compound with no structural analogues [Eu6(phen)6(dfb)14.7(bz)3.3] (4Eu4.9). According to single-crystal X-ray diffraction data, all carboxylate anion positions in the resulting mixed-anionic compounds were disordered and occupied simultaneously by bz-and dfb-anions in varying ratios. Variation of the anion ratio within the compounds allowed finetuning the system of structure-forming non-covalent interactions and influencing the molecular and supramolecular structure of the compounds and their photoluminescent properties. The obtained compounds were characterized by single-crystal and powder X-ray diffraction, infrared (IR) spectroscopy, simultaneous thermal analysis and CHN elemental analysis. Phase purity of compounds 1Eu0.6, 1Eu1.3, 1Eu1.6, 1Tb0.6, 2Eu2.7, 3Eu4.45, 3Eu5.05, 3Eu6 and 5Tb2.5 has been proven using powder X-ray diffraction. Furthermore, solid-state photoluminescence properties have been investigated for complexes 1Eu1.3, 1Tb0.6, 2Eu2.7, 3Eu4.45, 3Eu5.05, 3Eu6 and 5Tb2.5.
New copper trifluoroacetate complexes with 3-arylidene-1-pyrrolines as N-donor ligands were synthesized through the interaction of trifluoroacetic acid salts of 3-arylidene-1-pyrrolinium derivatives (L-X, where X = Cl, Br, F, Et, OMe, OEt, Me, OH) with copper acetate. These complexes exhibit diverse structural motifs: Cl- and Brsubstituted ligands form coordination polymers featuring octahedrally coordinated copper ions. Ligands bearing -F, -Et, -OMe, and -OEt substituents yield molecular complexes with square-planar copper environments. In the case of L-Me and L-Et derivatives the complexes of five-coordinated copper were obtained due to additional coordination of the water molecule. It is obvious that complexes with water molecules are formed due to their presence in the initial salts or solvent. Periodic quantum-chemical calculations of real and simulated polymeric and molecular complexes of Cu(L)2(CF3COO)2 composition showed that specific type of crystallization for each type of complexes is determined by thermodynamic reasons. The molecular docking method confirmed that 3-arylidene-1-pyrrolidonium derivatives (both in free and protonated forms) effectively interact with the HER2 receptor, demonstrating significant binding energies. Copper-based coordination compounds exhibit higher binding energies to HER2, indicating their increased potency compared to the parent ligands.
Seven new heterometallic 3,5-di- tert -butylbenzoate complexes with a {Co 2 Ln} metal core were synthesised and characterised by means of X-ray diffraction. Three of these complexes exhibit SMM behavior.
Using mixed-anion europium(III) compounds combining 2,4,6-trimethylbenzoate (tmb) and pentafluorobenzoate (pfb) anions with 1,10-phenanthroline (phen) or 2,2 '-bipyridine (2,2-bpy) as a model system, we demonstrate that variation of the initial reagent ratios as well as the synthesis and crystallization conditions enables control over the composition and crystal structure of the resulting compounds. A series of mixed-anion compounds different anion ratios was obtained:[Eu2(MeOH)2(phen)2(pfb)5(tmb)]center dot 4MeOH (1Eu), [Eu2(bpy)2(pfb)5(tmb)] (2Eu), [Eu2(phen)2(pfb)4(tmb)2] (3Eu),[Eu2(phen)2(pfb)4.4(tmb)1.6]center dot 4C6H6 (4Eu), as well as trimethylbenzoate compounds [Eu2(phen)2(tmb)6]center dot 7.4MeOH (5Eu_I), [Eu2(phen)2(tmb)6] (5Eu_II), and [Eu2(phen)2(tmb)6]center dot 2DMF (6Eu). Additionally, gadolinium compounds[Gd2(MeOH)2(phen)2(pfb)5.2(tmb)0.8]center dot 4MeOH (1Gd), [Gd2(phen)2(pfb)4(tmb)2]center dot 4C6H6 (4Gd), and [Gd2(phen)2(tmb)6]center dot 2DMF (6Gd), which are analogues of 1Eu, and 6Eu compounds, were obtained for a further interpretation of the photoluminescent properties. It was found that in compounds 1Eu, 1Gd, 2Eu, and 4Eu certain anion positions are disordered and simultaneously occupied by pfb-and tmb-anions in varying ratios. Additionally, introducing a second type of anion into these complexes enhances their photoluminescence properties while enabling fine control over the system of structure-directing non-covalent interactions and affects both the molecular and supramolecular structure of the compounds. obtained compounds were characterized by single-crystal and powder X-ray diffraction, infrared (IR) spectroscopy, and elemental (CHN) analysis. The solid-state photoluminescence properties were also investigated.
