Abstract
5-chloropyridine-2-carbaldehydethiosemicarbazone (HL1) and its nickel(II), cobalt(II), Zinc(II) and copper(II) complexes: [Ni(HL1)2], [Co(HL1)2], [Zn(HL1)2], [Cu(HL1)2], [Cu(HL1)], were synthesized and characterized. The ligand has been characterized by elemental analyses, IR, 1H NMR and Mass spectroscopy. The dentate nature of the ligand is evident from the spectral obtained data and literature.
