Studies on Complexes of Cu II And Zn II Metal Ions with 2-(Thiophene-2- Formylimino) Benzimidazole

C. V. Jose and T. Joy Anto

CuII and ZnII complexes with 2-(thiophene-2-formylimino)benzimidazole having ML2X2 stoichiometries have been reported (where X = Cl, NO3, CH3COO and C6H5COO). On the basis of elemental analysis, conductivity measurements, magnetic studies, IR and electronic spectral studies, the complexes were characterized. All the complexes show higher central nervous system (CNS) depressant activity and possess much higher toxicity as compared to the ligand.
