Complexes of Co(II), Ni(II), Cu(II) and Zn(II) with 6-substituted 4-aryl-3-cyano-pyridine-2-(1H)-thiones have been prepared and characterized by elemental analysis, IR, UV-Visible and 1H-NMR spectroscopy, molar conductivity, magnetic moment measurements and x-ray diffraction analysis.According to magnetic measurements and UV-Visible spectra, nickel(II) and copper(II) complexes are suggested to have square-planar structure whereas cobalt(II) complexes has either tetrehedral or square planar geometries.X-ray diffraction analyses suggested the orthorhombic powder structure unit for Ni(II) and Cu(II) copmlexes and triclinic for Co(II) ones. Key words: 6-Substituted-4-aryl-3-cyano-pyridine-2-(1H) thiones; pyridine-thione complexes; metal ion complexes; spectroscopy; magnetic moments; conductivity.
