Structural characterization of the water-soluble porphyrin complexes [Fe^II(TPPS) (NO^•)]^4─ and [μ-O-([Fe^III(TPPS)])₂]^8─.

ABSTRACT: Iron water-soluble porphyrins have been long used as biomimetic compounds for modelling the active sites found in heme-enzymes. In this regard, the anionic porphyrin [Fe^III(TPPS)]^3─ and its coordination complexes have been repeatedly chosen as suitable water-soluble platforms for bioinorganic chemistry studies. In this work we report for the first time the crystal structure of the water-soluble nitrosyl complex [Fe^II(TPPS) (NO^•)]^4─ along with that of oxodimeric ferric species [μ-O-([Fe^III(TPPS)])₂]^8─.
