A novel copper-organic polyacid complex [CuI(2,2 -bipy)2]{[CuII(2,2 -bipy)2]2(BW12O40)}•4H2O was synthesized by in-situ generation of 2,2 -bipyridine from 2,2 -bipyridine-3,3 -dicarboxylate precursor under hydrothermal condition and characterized by elemental analysis, IR, TG, CV and single-crystal X-ray diffraction. The title compound crystallized in a monoclinic crystal system, with space group P21/n, a＝1.88365(14) nm, b＝2.04178(15) nm, c＝2.16724(16) nm, α＝90°, β＝96.6720(10)°, γ＝90°, V＝8.2786(11) nm3, Z＝4, Dc＝3.255 g/cm3, R1＝0.0575, wR2＝0.1073. The compound consists of copper-organic polyoxoanion {[CuII(2,2 -bipy)2]2(BW12O40)}－, cations [CuI(2,2 -bipy)2]＋, lattice water molecules and formed a 2D supramolecular networks by hydrogen bond and π-π stacking of 2,2 -bipyridine. The cyclic voltammogram indicated that three couples redox waves were observed on the compound modified carbon paste electrode (1-CPE).

Key words: copper-organic polyacid complex, polyoxometalate, in-situ synthesis, crystal structure
