Abstract
A new organic–inorganic hybrid arsenomolybdate, formulated as, [{Cu(abi){H4AsIIIAsVMo9O34}](abi)4[Cu(abi)2]·H2O (1) (abi = 2-aminobenzimidazole) has been hydrothermally synthesized and structurally characterized by the elemental analysis, TG, IR, XRD, UV and single-crystal X-ray diffraction. Compound 1 represents the first example of monocapped trivacant Keggin {H4AsIIIAsVMo9O34}2− cluster as polydentate ligand linked to Cu–abi complexes and abi ligands through one covalent bond and fourteen hydrogen bonds. Compound 1 possesses two different four rings, which forms a 3D topology framework with schlafli symbol of {46·6·8·1820}{4}2{6}2{8}3. The photoluminescence and photocatalysis properties of 1 have been investigated. Moreover, we performed evaluation on its catalytic activity towards the hydrolysis of ethylene carbonate to produce ethylene glycol.
