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 [FeIII(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 [FeII(TPPS) (NO•)]4─ along with that of oxodimeric ferric species [μ-O-([FeIII(TPPS)])2]8─.
The crystal structure of biomimetic complex [FeII(TPPS) (NO•)]4─ is presented.
Ferric oxodimer [μ-O-([FeIII(TPPS)])2]8─ is also structurally characterized.
Both structures are described and compared to those of related complexes.
