Cu (CH3COO) 4 (C4H8N4) 2] .2CH3CN was prepared by reacting Cu (CH3COO) 2 with 4-amino 3,5 dimethyl 1,2,4 triazole. The crystal belongs to the triclinic system with a = 8.266 (2), b = 8.585 (2), c = 10.741 (2), α = 75.58 (3), β = 88.46 (3), γ = 86.35 ) °, V = 736.7 (3) 3, Z = 1, Dc = 1.509 g · cm 3, F (000) = 346, μ = 1.502 mm 1. X-ray diffraction analysis shows that the Cu2 (CH3COO) 4 (C4H8N4) 2 unit is a centrosymmetric binuclear complex with a distance of 2.698 between the two copper atoms. Each metal atom is surrounded by a tetragonal pyramidal coordination structure with the nearest four oxygen atoms of the four acetate ligands on the bottom [CuO = 1.965 (3) ~ 1.986 (3)], a 4 amino 3 , 5 dimethyl 1,2,4 triazole ligand at the apex position Cu N = 2.172.
