55-56The potentially bidentate ligand, N, N'-bis(2-phenylbenzimidazolyl)methane(BPBM) has been used to synthesize iron(III) complexes. 1H NMR spectra showed both upfield and downfield shifted peaks for ligand protons. The Mossbauer spectral data reveal the presence of high spin ferric ion and lower value of isomer shift indicates substantial covalency in Fe(III) ligand bond. The present Fe(lll) complexes appear to activate the oxidation of tetramethylphenylenediamine by molecular oxygen
