Synthesis, spectral and cyclic voltammetric studies of iron (III) complexes with N, N?¢????, N?¢???-tris-(benzimidazolyl)-methane ligand

Abstract

The tripodal ligand N, N’, N’’-tris-(Benzimidazolyl)-methane (TBM) containing benzimidazole as pendant groups has been synthesized and utilized to prepare Fe (III) complexes of general composition [Fe (TBM) X3]. n H2O. Where X is an exogenous anionic ligand(X=Cl-, NO3 -, CH3COO- & HCOO-). Complexes of 1:1 stochiometry form with the ligands in methanol and were characterized by elemental analysis, IR, UV-VIS spectroscopic and other analytical techniques. The cyclic voltammograms of the complexes were taken in DMSO. Cyclic Voltammetric measurement of the complexes display quasi reversible redox wave. The –ve reduction potential values reveal the strong binding of anionic donors stabilizing the Fe (II) oxidation state. The magnetic moment data reveal the monomeric nature. The IR spectral data reveal unidentate mode of binding of the benzimidazole and anionic donors to the iron site. The UV spectra reveal that the UV bands are all blue shifted upon coordination and in general in enhance in intensity. The large molar extinction coefficients reveal that the iron site in the complexes is of low symmetry. The complexes have been screened for their antibacterial and antifungal activity. The result of this study shows that the Fe (III) complexes are effective against the bacterial pathogens.
