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}3As3Mo3O15] · 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 image complexes through Ob⋯Ot⋯Ob (Ot, terminal oxygen; Ob, bridging oxygen) atoms. The electrochemical behavior and electrocatalysis of 1-modified carbon paste electrode (CPE) have been studied in detail.
