• sandwich-type
• electrocatalysis
• magnetic property

A new molybdovanadate, [HN(CH3)(3)](10)[Co-2(VMo9O33)(2)]center dot 8H(2)O (1) was synthesized by a conventional self-assembly reaction in aqueous solution and structurally characterized by elemental analysis, IR spectra, UV electronic spectroscopy, and X-ray diffraction. Compound 1 exhibits a sandwich-type framework based on molybdovanadate anions [VMo9O33](7-) linked by a dinuclear cobalt(II) cluster, which is a first observation in a sandwich-type molybdovanadate system. Electrocatalytic experiments show that 1 exhibits bifunctional electrocatalytic activities for the oxidation of dopamine (DA) and the reduction of IO3-. Magnetic measurements of 1 indicate the presence of antiferromagnetic interactions between cobalt ions.
