Synthesis and Crystal Structure of Binuclear Copper(I) Complex Through Reduction Reaction

Abstract

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, D_c=1.373 g.cm^-3, μ=90 cm^-1, R=0.026, R_w=0.028.
