A binuclear copper(Ⅰ) complex [Cu2(dppm)2(C7H6N2)2](NO3)2 (C7H6N2 = benzimidazole, dppm = Ph2PCH2PPh2) has been synthesized and characterized by X-ray crystallography.The crystal belongs to monoclinic, space group C2/c with a = 14.167(3), b = 21.209(4), c =20.680(4) A, β = 103.93(3)°, C32H28CuN3O3P2, Mr = 628.05, Z = 8,μ = 0.868 mm-1, V = 6031 (2)(。A)3,F(000) = 2592, Dc= 1.383 g/cm3, R = 0.0593 and wR = 0.1736.A total of 5297 independent reflec tions were collected, of which 3503 were observed with I ＞ 2σ(I).The central copper atom is tri-coordinated by phosphorus atoms from bridging dppm and nitrogen atom from benzimidazole.In the coordination sphere, the bond lengths of Cu-P(1) and Cu-P(2) are 2.2607(17) and 2.2503(16)(。A),respectively and the P-Cu-P bond angle is 127.26(6)°.
