| 摘 要： | <正>Self-organization of copper (I) ion with bridging ligand bis(diphenylphosphino)-acetylene resulted in the isolation of a dinuclear copper ( I ) complex Cu2(μ-Ph2PC≡ CPPh2)3(MeCN)2](ClO4)2·Et2O. Structural analysis indicated the existence of a helical coordination cage, in which two copper (I) atoms are bridged triply by the linear diphosphine Ph2PC≡CPPh2 with the CuACu separation of 6.231 A. The copper (I) atom is in an approximately tetrahedral environment with a NP3 coordination chromophore. The complex crystallizes in the triclinic, space group P 1 with a = 13.8456(2), b = 16.6010(1), c = 18.9215(3) A, α = 98.289(1), β = 91.232(1), γ = 106.496(1)°, V = 4117.60(9) A3, Z = 2, C86H82Cl2N2O9P6Cu2, Mr= 1659.37, Dc= 1.338 g/cm3, F(000) = 1708, μ = 0.754 mm-1, the final R = 0.0688 and wR = 0.1940 for 11692 reflections with I>2σ(I).
