| 摘 要： | 1 INTRODUCTION Procedures to synthesize copper(I) complexes are of great interest due to the diversity of products resulting from almost the same methodology. It has been long known that four-electron-donordipho- sphine compounds Ph2P(CH2)nPPh2 are excellent bi- dentate ligands1, 2]. The chelating tendency of bis- (diphenylphosphino) methane is one of the dipho- sphine ligands most suitable to lock two metal atoms together in close proximity3]. Many examples of bi- or polynuclear com…

| Abstract: | A binuclear copper(I) complex Cu2(dppm)2(C7H6N2)2](NO3)2 (C7H6N2 = benzimi- dazole, 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) ?, β = 103.93(3)o, C32H28CuN3O3P2, Mr = 628.05, Z = 8, μ = 0.868 mm-1, V = 6031(2) ?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) ?, respectively and the P–Cu–P bond angle is 127.26(6)o. |
