Antimicrobial relevance of Cu (II) complexes of thiophene-2-glyoxal-p-halogen substituted anils

Isomeric complexes of, p-chloro, p- bromo, and p-iodo – anils of 2-thiophene glyoxal ligands have been synthesized and characterized by metal analysis, molecular weight, infrared and UV-Visible spectroscopy, molar conductance and magnetic measurements. All non electrolytic complexes are square planar paramagnetics. Among all of the compounds only p-bromo and p-iodo-anils of 2-thiophene glyoxal exhibited good anti fungal activity against both test fungi but all products showed moderate to good bactericidal effect against S.aures and X.holicicola bacteria.
