摘　　要：A new nickel（Ⅱ） coordination complex [Ni（2,2＇-bipy）2（ClC6H4COO）（H2O）]（ClO4） was synthesized by self-assembly reaction of m-chlorobenzoic acid, 2,2＇-bipy and Ni（ClQ4h·6H2O. The crystal of the title compound belongs to monoclinic system, space group P2（1/n） with a = 0.77764（14）, b = 2.6572（5）, c = 1.3637（2） nm, β = 96.456（3）°, V= 2.8000（9） nm^3, D,, = 1.528 g/cm^3, Z = 4, Mr = 644.10, μ（MoKα） = 0.937 mm^-1, F（000） =1320, R = 0.0549 and wR = 0.1164. Structure analysis shows that the nickel（Ⅱ） ion is coordinated with four nitrogen atoms from two bipys as well as two oxygen atoms from m-chlorobenzoic acid and water, respectively, giving a distorted octahedral coordination geometry. The cyclic voltametric behavior of the complex is also presented.A new nickel（Ⅱ） coordination complex [Ni（2,2＇-bipy）2（ClC6H4COO）（H2O）]（ClO4） was synthesized by self-assembly reaction of m-chlorobenzoic acid, 2,2＇-bipy and Ni（ClQ4h·6H2O.
