A new dinuclear copper(Ⅱ) complex [Cu(CH3COO)(C7H5N4)(H2O)]2·3.5H2 O has been hydrothermally synthesized with copper acetate, o-acetamidobenzoic acid and 3-(pyridin-2-yl)-1,2,4-triazole. It crystallizes in the monoclinic space group P21/c, with a = 12.0188(7), b = 13.7993(8), c = 8.7488(5) ?, β = 101.7350(10)o, V = 1420.67(14) ?3, D3 c = 1.568 g/cm, Z = 1, F(000) = 690, the final GOOF = 1.145, R = 0.0437, and w R = 0.1097. The crystal structure shows that the whole molecule consists of two copper ions bridged by two μ2-η1:η0 3-(pyridin-2-yl)-1,2,4-triazole anions. The coordination environment of Cu(Ⅱ) ion is Cu O2N3, giving a distorted square pyramidal geometry. The thermal stability and magnetic properties of the complex were investigated.
