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=0.741(2)(A)3, α=75.58(3), β=88.46(3), γ=86.35(3)°, V=736.7(3)(A)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 (A). 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)(A)] 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 (A).
