A new series of thiocarbamides was prepared by the reaction of benzoylisothiocyanate with various amines namely 2-amino-pyridine (H2LI), 3-aminopyridine (H2LII), 2,3-diaminopyridine (H2LIII), 2,6-diaminopyridine (H2LIV), o-phenylenediamine (H2LV) and ethylenediamine (H2LVI).The nickel (II) complexes of these ligands were isolated and have been characterized by elemental analyses, molar conductivities, magnetic moments and spectral (visible, IR) measurements.IR spectra show that the ligands behave as a dianionic or neutral tetradentate ligand, as monoanionic tridendate ligand or as neutral bidendate ligand.Magnetic measurements and spectral analysis suggest that Ni(LV) and VI)>2 are square plane, Ni(HLII)2H2O being associated with a tetrahedral-square planar isomerism and the other complexes are tetragonally distorted octahedral.All the complexes are non-electrolytes.
