ABSTRACT:

A novel ligand,  N'-[-phenylmethylidene]benzenecarbothiohydrazide  was synthesized by the reaction of  benzenecarbothiohydrazide and benzaldehyde in 1:1 ratio. The Co(II), Ni(II), Cu(II) and Zn(II) derivatives of N'-[-phenylmethylidene]benzenecarbothiohydrazide  were also synthesized. The ligand and metal complexes were characterized based on molecular weight, IR, electronic spectra, 1HNMR and 13CNMR. Their spectroscopic characterization suggested coordination of the ligand to the metal ions through the >C=N and C=S. The complexes with [M(L)2] showed a square-planar geometry.
