A new [As3Mo3O15](3-) fragment decorated with Cu(I)-imi (imi = imidazole) complexes: Synthesis, structure and electrochemical properties

A novel molybdenum arsenate compound [{Cu(imi)(2)}(3)As3Mo3O15]center dot H2O (imi = imidazole) 1, has been prepared by hydrothermal method and structurally characterized by elemental analysis, IR, XPS, TG analysis and single-crystal X-ray diffraction analysis. Compound 1 represents the first example of molybdenum arsenate fragment [As3Mo3O15](3-) as polydentate ligand covalently bonded to three [Cu-I(imi)(2)] complexes through O-b center dot center dot center dot O-t center dot center dot center dot O-b (O-t, terminal oxygen: O-b, bridging oxygen) atoms. The electrochemical behavior and electrocatalysis of 1-modified carbon paste electrode (CPE) have been studied in detail. (C) 2008 Elsevier B.V. All rights reserved.
