Synthesis and Characterization of Psychopharmacologically Active Complexes of Copper(II) and Zinc(II) with 2-(Furan-2-formylimino)benzimidazole

Abstract

Synthesis of Cu(II) and Zn(II) complexes with 2-(furan-2-formylimino)benzimidazole having ML₂X₂ stoichiometries have been reported (where X = Cl^–, NO₃^–, CH₃COO^– and C₆H₅COO^–). Characterizations have been done on the basis of elemental analysis, conductivity, magnetic, IR and electronic spectral studies. Complexes have been found psychopharmocologically more effective in taming and hypnotic activities and possess much higher toxicity as compared to the ligand.
