ABSTRACT:

A new tetradentate Bis-benzimidazole based ligand, N-Octyl-N,N’-Bis-(2-Methyl-Benzimidazoly)-benzene-1, 3-dicarboxamide(O-GBBA) has been synthesized and utilized to prepare Iron (III) complexes of general composition [Fe(O-GBBA)X₂].X.nH2O where X is an exogenous anionic ligand (X=Cl-, NO₃-). These complexes were prepared in the molar ratios of metal: ligand (1:1) and characterized by elemental analysis, IR, UV spectroscopic and other analytical techniques. Cyclic voltammetric measurements of the complexes display quasi reversible redox wave due to the Iron (III)/Iron (II) process. The distorted octahedral geometry with monomeric composition was proposed for both theses complexes on the basis of these studies. These complexes have been screened for their antimicrobial activities against bacteria, Lactobacillus and fungi, A.Niger, Rhizopus & Mucer. These complexes were found to exhibit considerable antimicrobial activity.
