Complexes of 1-picolinoly-4-phenyl-3-thiosemicarbazide (H2PTS) with Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Hg(II) and UO2(VI) have been synthesized and characterized on the basis of elemental analyses, molar conductivities, magnetic moment and spectral (IR and visible) studies. IR spectral data show that H2PTS behaves in a monoanionic bidentate or tetradentate and bianionic tetradentate manner. All complexes are non-electrolytes. An octahedral structure is proposed for the Cr(III), Mn(II), Fe(III), Co(II) and Ni(II) complexes, while a square-planar one is suggested for Cu(HPTS)Cl.H2O and Cu(PTS) according to the data of magnetic and electronic spectral measurements.
