Nickel(II) complexes of thiocarbohydrazones were prepared by reacting nickel(II) chloride with the appropriate thiocarbohydrazones in an alcoholic medium.The complexes are brownish in colour and analyze for 1:1 stoichiometry of the type NiL.The molecular weight determination in nitrobenzene indicates that the complexes are monomeric in nature.These are diamagnetic, and optical spectra support this conclusion.The infrared spectra of the complexes compared with those of the ligands suggest that hydroxy groups of the ligands are involved in bond formation with the Ni(II) moiety via deprotonation.The -C=N groups form coordinate bonds through N atom of the azomethine group.The S atom of the ligand does not take part in coordinate bond formation.Assignments have been made in the low frequency region (600-200 cm-1).The various bands found in this region are assigned to ν(Ni-N) and γ(NiO) modes.All these observations point to a square planar configuration for these complexes and focus upon non-involvement of the -S- group in the bond.Thus ligands in these complexes show a tetradentate behaviour by keeping the S group away from coordination.
