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 Cu(Cu 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 ī with a = 13.8456(2), b = 16.6010(1), c = 18.9215(3)(A), ( = 98.289(1), ( = 91.232(1), ( = 106.496(1)(, V = 4117.60(9) (A)3, Z = 2, C86H82Cl2N2O9P6Cu2, Mr = 1659.37, Dc = 1.338 g/cm3, F(000) = 1708, ( = 0.754 mm-1, the final R = 0.0688 and wR = 0.1940 for 11692 reflections with I > 2((I).
