摘要： 铜(Ⅰ)配合物由于其变化奇异的结构、性质及配位数而引起化学工作者的广泛兴趣.四电子供体双二苯基膦甲烷(dppm)适宜在近距离内与2个金属原子同时配位,容易形成八元环的二聚体M2P4C2,因而是桥联2个低氧化态过渡金属的最佳选择.

Abstract: Binuclear copper(Ⅰ) complex [Cu2(dppm)2(Py)2(NO3)](NO3)·CH3OH(2), Py=pyridine, dppm=bi(diphenylphosphine)methane has been synthesized by ligand reduction of cupric nitrate with dppm and characterized by means of specific elemental analyses, molecular weight determination, 31PNMR and electronic conductivity measurement. The X-ray crystal structure of complex (2) shows that dppm coordinates as a bridging bidentate ligand to the two Cu(Ⅰ) atoms, and two NO3behave as a bidentate ligand and an outer sphere respectively in the newly prepared binuclear copper(Ⅰ) complex. The crystal is monoclinic, space group P21with unit cell parameters a=1.3650(4) nm, c=1.3653(2) nm, b=1.5970(7) nm; β=105.4(2)°, Z=2, V=2.8689nm3, F(000)=1252, Dc=1.373 g.cm-3, μ=90 cm-1, R=0.026, Rw=0.028.
