A new mononuclear copper(Ⅱ) complex [(bipy)2Cu(PhCOO)]ClO4·(benzil) (bipy = 2,2′-bipyridine, benzil = 1,2-diphenyl-ethane-1,2-dione) was synthesized by direct electrochemical oxidation of Cu electrode in an acetonitrile solution with benzoic acid, 2,2′-bipyridine and benzoin. As soon as the current flowed in the cell, benzoin was oxidized to benzil quickly. The crystal structure was determined by X-ray diffraction. It belongs to monoclinic system, space group P21/c with a = 14.860(2), b = 20.784(3), c = 11.9150(17) , β = 101.401(3)°, V = 3607.3(9) 3, Z = 4, Mr = 806.69, Dc = 1.485 g/cm3, F(000) = 1660, μ = 0.742 mm-1, R = 0.0788 and wR = 0.1519 for 6254 observed reflections (I > 2σ(I)). The complex contains a mononuclear [(bipy)2Cu(PhCOO)]+ cation, a solvate benzil molecule and a ClO4- anion which locates around the cation outside acting as the counter ion. The Cu(Ⅱ) ion is coordinated by two 2,2′-bipyridines and one benzoato ligand to form a distorted square-pyramid.
