Abstract

High-spin ferrous metalloporphyrins FeII(NCH3TPP)Cl, FeII(NCH3TPP)Br, FeII(NCH3TPP)ClO4, and FeII(NCH3OEP)Cl(NCH3TPP-N-methyltetraphenylporphyrin, NCH3OEP-N-methyloctaethylporphyrin) have been characterized by Mössbauer spectroscopy. Values ofIS (0.8 mm/s versus α-Fe) typical for high-spin ferrous porphyrin and very large quadrupole splittings (≊4 mm/s) have been observed. Iron(II) N-methylporphyrins should be readily detected in proteins by means of Mössbauer spectroscopy. Such parameters are similar to those of symmetrical anionic five coordinate high-spin porphyrins [FeII(TPP)X] (X-halide).
