摘　　要：在甲醇溶剂中以三苯基膦直接还原硝酸铜得到一价铜化合物 [Cu(Ph3 P) 2 (NO3 ) ],并通过元素分析 ,红外光谱 ,电导测定及X -射线四圆衍射表征了配合物的结构和性质 ,晶体属于三斜晶系 ,空间群为P - 1,晶胞参数如下 :a =0 .0 9193(2 ) ,b =1.310 6 (6 ) ,c =1.85 (6 )nm ;α =6 4.78(3)° ,β =72 .80 (3)°,γ =6 9.44 (3)°,V =1.5 5 6 4nm3 ,Z =2 ,F(0 0 0 ) =6 72 ,Dcalc=1.387g .cm3 ,R =0 .0 335 4,Rw =0 .0 3733。分析结果表明 ,配合物中除三苯基膦参加配位外 ,硝酸根属于双齿配位。Mononuclear copper(Ⅰ) complex [Cu(PPh\-3)\-2(NO\-3)] has been synthesized by ligand reduction of cupric nitrate with PPh\-3 in methanol and characterized by speclic elemental analyses, molecular weight determination, IR spectra and X-ray single crystal analysis; its electronic conductivity has also been measured. The crystal is triclinic, space group P-1, a=0.09193(2), b=1.3106(6), c=1.85(6)nm; α=64.78(3)°, β=72.80(3)°, γ=69.44(3)°, V=1.5564 nm\+3, Z=2, F(000)=672, D\-\{calc\}=1.387g.cm\+3, R=0.03354, Rw=0.03733. The results show that PPh\-3 coordinates as mono-dentate ligand to the Cu(Ⅰ) atoms, and (NO\-3) behaves as a bidentate ligand in the prepared complex.
