Обобщены актуальные направления исследований в области металл-органических координационных полимеров (МОКП), проводимых в научных организациях и университетах России в последние 5—10 лет. Обзор охватывает вопросы дизайна, синтеза, топологического описания и прогнозирования свойств МОКП, разработки способов их химического конструирования и модификации, изучения современными физико-химическими методами, создания функциональных материалов на основе пористых каркасов (гетерогенных катализаторов, высокоэффективных и высокоселективных сорбентов нового поколения, проводящих материалов, систем для адресной доставки лекарств).
New trinuclear Cd–Ln molecular complexes [EuCd 2 (O 2 CC 6 F 5 ) 6 (NO 3 )(Bipy) 2 ] ( I , Bipy is 2,2'-bipyridine) and [LnCd 2 (Bzo) 6 (NO 3 )(Phen) 2 ] · 4MeCN (Ln = Tb ( II) , Eu ( III ), Bzo is anion of 3,5-di- tert -butylbenzoic acid, Phen is 1,10-phenanthroline) are studied. Their structures are determined by X-ray structure analysis (СIF files CCDC nos. 1938125 ( I ), 1938124 ( II )) or by X-ray diffraction analysis ( III ), and the photoluminescence properties are studied. The reactions of complexes I and II with terephthalic acid (H 2 Bdc) are accompanied by the destruction of the heterometallic molecules to form 2D coordination polymers [Cd 3 (Bbdc) 3 (Bipy) 2 ] 3 n · 4 n MeCN · n H 2 O ( IV ) and [Cd 2 (Bdc) 2 (Phen) 2 ] n · 2 n DMF ( V ) (СIF files CCDC nos. 1938126 and 1937492, respectively).
Heterometallic malonate complexes [Ag2Ni(H2O)2(R2mal)2]n (R2mal2– is the dimethylmalonate dianion (Me2mal2–) (1) or the cyclobutane-1,1-dicarboxylate dianion (Cbdc2–) (2)) and [Ag2Cu(H2O)(Me2mal)2]n (3) were synthesized. The bis-chelate fragment {M(R2mal)2} (M = Ni, Cu) composed of two dianions of an acid and a 3d metal atom is the structure-forming unit of these complexes. The mononuclear fragments are linked by silver(I) atoms, which are involved in argentophilic interactions, to form 2D coordination polymers.
Using the TOPOS structure-topological software, topological analysis and systematization of the underlying nets of 574 framework coordination polymers based on iron, cobalt, or nickel complexes was carried out. Highly symmetrical networks with relatively low C.N. values and simple coordination figures were found to predominate. The key factors dictating the topology of the underlying net were identified and a general scheme for the design of coordination polymer frameworks was proposed.
