摘　　要：通过金属铜粉和过氧化苯甲酰的氧化加成反应合成了双核铜配合物[Gu_2(OPPh_3)_2(C_6H_5CO_2)_4],以元素分析、IR,TG、磁性及粉末衍射表征了配合物的结构,并对其单晶进行了X射线衍射分析,晶体属于单斜晶系,A2/a空间群,晶胞参数为:a=2.4337(3),b=1.0566(1),c=2.1579(2)am;β=93.18(1)°,V=5.540(1)nm^3,Z=4,F(000)=2408,D_o=1.400,D_0=1.40 g·cm^(-3),μ=9.1cm^(-1),最终偏离因子R=0.042,R_W0.044。Dibenzoyl peroxide undergoes oxidative addition reaction with metallic copper powder and triphenylphosphine, which affords product as a binuclear complex, [Cu_2(OPPh_3)_2(C_6H_5CO_2)4]. The structure of the complex was characterized by elemental analyses, IR, TG and X-ray powder diffraction. Crystals are monoclinic, space group A2/a, a=2.4387(3), b=1.0556(1), c=2.1579(2)nm, Z=4, β=93.18(1)°, V=5.540(1)nm^3, R=0.042, R_w=0.044, Each copper ion is coordinated by four bridging benzoato oxygens and one triphenylphosphine oxide to form a dimeric binuclear molecule.
