【Abstract】 Single crystals of the new title compound [Cu2(CH3COO)4(C4H8N4)2]·2CH3CN are obtained from the reaction of Cu(CH3COO)2 and 4 amino 3,5 dimethyl 1,2,4 triazole. It crystallizes in the triclinic space group P1, with a = 8.266(2), b = 8.585(2), c = 10.741(2) ?, α= 75.58(3), β= 88.46(3), γ= 86.35(3)°, V = 736.7(3) ?3, Z = 1, Dc = 1.509 g·cm 3, F(000) = 346, μ= 1.502 mm 1. X ray crystal structure analysis revealed that Cu2(CH3COO)4(C4H8N4)2 unit is a crystallographically centrosymmetric binuclear complex, with Cu atoms distance Cu(1) Cu(1A) of 2.698 ?. Each metal atom is coordinated in a square pyramidal environment by four nearest oxygen atoms from four acetate ligands [Cu O = 1.965(3)～1.986(3)?] on the basal plane, and one 4 amino 3,5 dimethyl 1,2,4 triazole ligand at the apical position with Cu N = 2.172 ?.更多还原
