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［１］，因而是桥联２个低氧化态过渡金属的最佳选择．由于在Ｍ２（ｄｐ...Binuclear copper(Ⅰ) complex [Cu 2(dppm) 2(Py) 2(NO 3)](NO 3)·CH 3OH(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, 31 P NMR 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 NO 3 behave as a bidentate ligand and an outer sphere respectively in the newly prepared binuclear copper(Ⅰ) complex. The crystal is monoclinic, space group P 2 1 with unit cell parameters a =1.365 0(4) nm, c =1.365 3(2) nm, b =1.597 0(7) nm; β =105.4(2)°, Z =2, V =2.868 9 nm 3, F (000)=1 252, D c=1.373 g.cm -3 , μ =9 0 cm -1 , R =0.026, R w =0.028.
