An unprecedented iron(III) complex supported by an asymmetric N-capped tripodal ligand incorporating the NO2S donor set

The synthesis of an iron(III) complex [Fe(L)(1-Meim)] (1-Meim = 1-methylimidazole) coordinated by an asymmetric N-capped tripodal tetradentate ligand (L) equipped with three aromatic arms is described. X-ray crystallographic analysis shows that the complex adopts a distorted bipyramidal geometry with a new type of N2O2S coordination environment around the iron centre.

The synthesis and structural characterization of an iron(III) complex [Fe(L)(1-Meim)] (1-Meim = 1-methylimidazole) coordinated by an asymmetric N-capped tripodal tetradentate ligand (L) bearing a new NO2S donor set are described.Figure optionsDownload as PowerPoint slide
