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(TPPS)] 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(TPPS) (NO)] along with that of oxodimeric ferric species [μ-O-([Fe(TPPS)])].
水溶性铁卟啉长期以来一直被用作仿生化合物，用于模拟血红素酶中的活性位点。在这方面，阴离子卟啉[Fe(TPPS)]及其配位络合物已被反复选为生物无机化学研究的合适水溶性平台。在这项工作中，我们首次报道了水溶性亚硝酰络合物[Fe(TPPS)(NO)]以及二聚铁(III)物种[μ-O-([Fe(TPPS)])]的晶体结构。
