The titled Schiff base (benzme) was synthesized by the condensation of S-methyl dithiocarbazate with benzaldehyde mustard in a 1:1 molar ratio. Dark yellow crystals of the Schiff base was formed. General formula of Schiff base being C13H17N3S2Cl2 and m.p. was found to be 180°C. The Schiff base reacts with divalent metal ions(Co(II) and Ni(II)) to form the neutral metal complex [Co(benzme)2] & [Ni(benzme)2]. The Schiff base and their metal complexes have been characterized by a variety of physico-chemical techniques, viz. elemental analyses, IR, Mass, 1HNMR and electronic spectral studies. The Schiff base behaved as uninegatively charged bidentate ligand. IR and 1HNMR spectral evidence indicate that the Schiff base coordinates to the Co(II) and Ni(II) ion via the azomethine nitrogen atom and the thiolo sulfur atom.
