摘 要: | A new dinuclear copper complex, [Cu(C9H11N3)Cl2]2(C18H22Cl4Cu2N6), has been synthesized and characterized by X-ray structure determination. It crystallizes in the triclinic P1^- space group with a = 7.526(3), b = 9.473(4), c = 9.535(3)A, α = 117.214(10), β = 108.251(9), γ = 91.560(6)°, V = 562.3(4)A^3, Z = 1, Mr = 591.30, F(000) = 298, Dc = 1.746 g/cm^3, μ(MoKα) = 2.385 mm^-1, the final R = 0.0577 and wR = 0.1248 for 2188 unique reflections with 1629 observed ones (Ⅰ〉 2σ(Ⅰ)). In the title complex, each copper(Ⅱ) atom is located at the center of a distorted trigonal bipyramid of five coordination atoms (two nitrogen and three chlorine atoms). Two copper(Ⅱ) atoms were bridged by two chlorine anions (Cl(2) and Cl(2a)) to form a Cu(Ⅱ)-Cu(Ⅱ) binuclear entity with the distance between two copper(Ⅱ) atoms of 3.398 (A).
