Chemical oxidation of tetradurylporphyrinatoiron(III) chloride followed by the addition of 2-methylimidazole at -78 °C gave the first example of the low spin ferric porphyrin radical cation with orienta ionally fixed imidazole ligands, [Fe(TDṖ)(2-MeIm)2]2+. The degree of asymmetric spin distribution on the pyrrole β carbons in the radical cation was estimated to be close to that in the starting low spin complex, [Fe(TDP)(2-MeIm)2]+, which was ascribed to the orthogonality of porphyrin a2u with imidazole π orbitals.
