Mononuclear copper( Ⅰ ) complex [Cu(PPh3)2(BH4)] has been synthesized by ligand replacement reaction in methanol and characterized by elemental analyses, molecular weight determination, IR spectra and X-ray single crystal analysis,its conductivity has also been measured. The crystal is monoclinic, space group C2/c, a =24.776(4), b=9.173(7), c=15.564(2)A; β=116.10(1)°, V=3176.73 A3, Z =4, F(000)=1256, μ(MoKα)=8.11 cm-1, Dc=1. 26 g/cm3, M=602.79, R=0. 039, Rw= 0. 050. The results show that PPh3 coordinates as monodentate ligand to the Cu ( Ⅰ ) atoms, and BH4 behaves as a bidentate ligand in the prepared complex.The central copper atom belongs to tetrahedron coordination geometry.
