The synthesis of ligand (HL) was based on multi-steps synthetic procedure. The reaction of 4-methylsulfanyl-benzoyl chloride with hydrazine gave 4-methylsulfanyl-benzoic acid hydrazide. This compound was reacted with carbon disulfide and potassium hydroxide in methanol to yield N'-(4-methylsulfanyl-benzoyl)-hydrazine potassium thiocarbamate, which upon reaction with methyl iodide resulted in the formation of the ligand. A range of physico-chemical techniques was used to characterise the new ligand and its mixed-ligand metal complexes. These include; IR, UV-Vis, 1H, 13C NMR, elemental micro analyses, magnetic susceptibility, atomic absorption, chloride content, and melting point. The physico-chemical analyses indicated the formation of complexes of the general formula [M(L)2X], (X = ethylene diamine (en), 2,2` bipyridine`(bipy) and 1,10 phenanthroline` (phen)), in which the coordination sphere about metal centre is octahedral.
