摘　　要：In this work,a cis-dicyanoiron(Ⅱ)building block,cis-FeⅡ(bpy)2(CN)2(1,bpy=2,2?-bipyridine),has been prepared and fully characterized by IR,electronic absorption spectra,elemental analysis,cyclic voltammetry and single-crystal X-ray diffraction analysis.The interactions of complex 1 with selected metal ions,such as Cu(Ⅱ),Fe(Ⅲ),Pb(Ⅱ),Fe(Ⅱ),Cr(Ⅲ),Cd(Ⅱ),Co(Ⅱ),Zn(Ⅱ),Ni(Ⅱ)and Mn(Ⅱ),were investigated employing electronic absorption spectroscopy.The electronic absorption spectroscopy indicates Cu(Ⅱ),Fe(Ⅲ),Cr(Ⅲ),Cd(Ⅱ),Co(Ⅱ),Zn(Ⅱ)and Ni(Ⅱ)ions steadily coordinate with 1 via cyanide,respectively.Fluorescent emission intensity of 1 increased upon the addition of Zn(Ⅱ)ion,quenched by adding ions Cu(Ⅱ),Fe(Ⅲ)and Pb(Ⅱ),and it was almost unchanged when adding the Fe(Ⅱ),Cr(Ⅲ),Cd(Ⅱ),Co(Ⅱ),Ni(Ⅱ)and Mn(Ⅱ)ions.
