The hydroxyl-bridged binuclear copper(Ⅱ) compound[Cu2(bipy)2(OH)2] (ClO4)2 (bipy=2,2′-bipyridine) has been prepared and its crystal structure determined by X-ray diffraction methods, crystallizes in the Triclinic system, space group C2/m, with a = 13.569(3), b = 15.212(3), c = 6.2715(10)A, β = 113.620(10)°, V = 1 188.4(4)A3,Dc = 1.879 g/m3, Z = 2, C20H18Cl2Cu2N4O10, Mr = 672.36, F(000) = 676.0. The structure consists of a binuclear cation [Cu(bipy)2(OH)2]2+ and two coordinated weakly perchlorates. Within each cation the two copper(Ⅱ) ions linked through two hydroxo-groups bridges, the copper(Ⅱ) atoms exhibited a CuO2N2 square planar geometry. The weak interactions existed as the intramolecular weak coordination bonds of Cu(1)...O(3) from the perchlorate, and two intermolecular hydrogen bonds of O(1)-H(1)A...O(2) and C(1)-H(1)B...O(2).
