| 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 CuaBr4 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： C_60H_56Br_4Cu_4N_4P_4, Mr= 1530.77, triclinic, space group P1, a = 11.6593（9）, b = 11.7181（9）, c = 13.8711（11） А, a = 110.1020（10）, β = 102.0050（10）, γ = 109.8040（10）°, V = 1557.5（2） А^3, Z = 1, Dc = 1.632 g/cm^3, F（000） = 760, λ= 0.71073А, T = 298（2） K, 2θmax = 50.04°,μ= 4.056 mm^-1, S = 1.181, R = 0.0507 and wR = 0.1025.
