摘　　要：A new dinuclear copper complex, [Cu（C13HgN2O）Cl]2.（CH3CN）2 （C30H24C12Cu2N6O2）, has been synthesized and characterized by X-ray structure determination. It crystallizes in the triclirile system, space group P1, with a = 7.6677（14）, b = 9.2375（17）, c = 11.227（2） ]A, α = 81.338（3）,β = 88.173（4）, γ = 66.199（3）°, V = 718.9（2） ]A^3, Z = 1, Mr = 698.53, F（000） = 354, Dc = 1.613 g/cm^3, μ（MoKa） = 1.705 mm^-1, the final R = 0.0645 and wR = 0.1364 for 2474 unique reflections with 1809 observed ones （I 〉 20（I））. In the title complex, each copper（H） atom is located at the center of a distorted tetrahedron consisting of four coordinate atoms （one nitrogen atom, two oxygen anions, and one chlorine atom）. Two copper（Ⅱ） atoms are bridged by two oxygen anions （O（1） and O（la）） of two phenolates to form a Cu（Ⅱ）-Cu（Ⅱ） binuclear entity, and the distance between two copper（Ⅱ） atoms is 3.0144（15） A.A new dinuclear copper complex, [Cu（C13HgN2O）Cl]2.（CH3CN）2 （C30H24C12Cu2N6O2）, has been synthesized and characterized by X-ray structure determination.
