An Organic–Inorganic Hybrid Polymer Based on Molybdenum(V) Phosphate and Cadmium(II) Complex

An unusual organic–inorganic hybrid polymer, [Cd(pztt)(H 2 O) 2 ] 4 [CdMo 12 V O 24 (OH) 6 (HPO 4 ) 4 (H 2 PO 4 ) 2 (PO 4 ) 2 ]·10H 2 O (pztt = 3-(pyrazin-2-yl)-5-(1H-1,2,4-triazol-3-yl)-1,2,4-triazliyi) ( 1 ), have been hydrothermally synthesized and structurally characterized by the elemental analysis, TG, IR, UV–Vis, PXRD and the single-crystal X-ray diffraction. In compound 1 , the sandwich-type {Cd[Mo 6 P 4 O 31 ] 2 } units are modified with Cd(pztt)(H 2 O) 2 fragments to lead bi-supported dimer clusters, which are further linked by binuclear complex subunits [Cd 2 (pztt) 2 (H 2 O) 4 ] to yield unusual 1-D chains. The 1-D chains are further packed into 2-D and 3-D supramolecular assemblies via strong hydrogen-bonding interactions. In addition, the electrochemical behavior of 1 -CPE and the photoluminescence properties of 1 in the solid state at room temperature have been investigated in detail.
