| 摘 要： | The vinylidenebis(diphenylphosphine) (vdpp) reacts with CuBr to give a tetranuclear complex, Cu4(μ3-Br)2(μ2-Br)2(μ2-vdpp)2(CH3CN)2]·(CH3CN)2 1. The title complex has crystallo-graphically imposed centrosymmetry and presents a Cu4Br4 core with distorted stair-like structure. All copper(Ⅰ) atoms in 1 assume distorted tetrahedral coordination geometry. The distance of 2.7745(11) A between the two copper centers indicates the presence of ligand-supported Cu…Cu interactions. Crystal data for 1: C60H56Br4Cu4N4P4, Mr = 1530.77, triclinic, space group P1, a = 11.6593(9), b = 11.7181(9), c = 13.8711(11) A, α = 110.1020(10), ,β = 102.0050(10), γ = 109.8040(10)°, V = 1557.5(2) A3, Z = 1, Dc = 1.632 g/cm3, F(000) = 760, λ = 0.71073 A, T = 298(2) K, 2θmax = 50.04°,μ = 4.056 mm-1, S = 1.181, R = 0.0507 and wR = 0.1025.
