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 .

Abstract：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 .
