Abstract :

The present work describes the synthesis and characterization of a few Mn(III) porphyrins with imidazole. A new series of high-spin Mn(III) porphyrins having general formulae [Mn(THMPP)X] and [Mn(THMPP)X(Im)], where THMPP =  Tetrakis(4-hydroxy-3-methoxyphenyl) porphinato ligand, X = Cl−, Br−, N3- or NCS− and Im = Imidazole have been synthesized. These complexes have been characterized by UV-visible, FT-IR, ESI-MS spectra, elemental analysis and magnetic susceptibility measurements. The tentative structures have also been proposed to be square pyramidal and octahedral respectively. These complexes will be studied for their applications in various organic transformation reactions as well as the depolymerization activity towards humic acid model compound. Keywords- Mn(III) porphyrin, Imidazole, Tetrakis(4-hydroxy-3-methoxyphenyl)porphine, FT-IR, ESI-MS.
