  • Abstract

    A ligand 5-Substituted-(2-methylbenzimidazol-1-yl)-1,3,4-oxadiazole-2-thione (L) and its Fe(III),Hg(II),Sn(II) and Zn(II) complexes were synthesized. The authenticity of the ligand and its transition metal complexes were established by elemental analyses, conductance and magnetic susceptibility measurements, as well as spectroscopic (IR, 1H NMR, UV–Vis and Mass) and thermal studies. All complexes exhibit the composition ML2X2 where M =Fe(III),Hg(II), Zn(II) and Sn(II), L=Ligand, X=OAc and chloride ions. The IR spectral studies revealed the existence thiol-thione tautamerism in the ligand molecule. The ligand acts as a bidentate coordinating through the N-3 nitrogen and the exocyclic sulfur atoms of ox diazole rings. Antimicrobial screening of the ligand and its metal complexes were determined against the bacteria Escherichia coli and Salmonella paratyphi A.
