A non-innocent pincer H3LONS ligand and its corresponding octahedral low-spin Fe(iii) complex formation via ligand-centric homolytic S–S bond scission

Abstract

In the presence of FeCl₃ and Et₃N, a ligand H₄L^dtda(AP) underwent S–S bond cleavage and generated a pincer non-innocent H₃L^ONS ligand, which formed a homoleptic, six-coordinate, low-spin Fe(III) complex (1). The complex comprised two 2-iminobenzosemiquinone (1⁻) π-radicals and one thiyl π-radical.
