摘　　要：A mixed-ligands complex with the formula of [Cu(R-lact)(o-phen)(H2O)]·4H2O was synthesized by the reaction of copper carbonate with racemic lactic acid(RS-H2lact), and then with o-phenanthroline(o-phen) in ethanol-water(95%) solution. One of the two obtained compounds was dark blue column single crystal and was characterized by elemental analysis, IR spectrum and X-ray single crystal diffraction. The crystal belongs to triclinic system with space group P1, a=7.2825(5), b=11.7322(8), c=12.1194(8), α=65.8280(10)°, β=84.2120(10)°,γ=75.3290(10)°, V=913.88(11)3, Z=2, Dc=1533kg·m-3, Mr=421.89, μ(Mo K\α)=1.240mm-1,λ =0.71073, the final R =0.0483 and ωR =0.1199 [I>2σ(I)] for 3120 observed reflections,F(000)=438. The copper atom is five coordinated with the distorted square pyramid environment.The five coordinated atoms are two oxygen atoms of depronated hydroxyl group and carboxyl of H2 lact, two nitrogen atom of o-phen and one oxygen atom of water molecule.A mixed-ligands complex with the formula of [Cu（R-lact）（o-phen）（H2O）]？4H2O was synthesized by the reaction of copper carbonate with racemic lactic acid （RS-H2lact）, and then with o-phenanthroline（o-phen） in ethanol-water（95%） solution.
