Exploring Mn-O bonding in the context of an electronically flexible secondary coordination sphere: synthesis of a Mn(III)-oxo.
Complexes containing manganese-oxygen bonds have been implicated in a variety of biological and synthetic processes. Herein, we describe the synthesis of a family of stable, high-spin trigonal bipyramidal manganese complexes of the electronically flexible ligand tris(5-cyclohexylimino-pyrrol-2-ylmethyl)amine [H3N(pi(Cy))3] featuring apical water, hydroxyl, and oxo ligands. Terminal Mn(III)-O complexes are rare and the formation of this species was achieved from a variety of reagents including O2, PhIO and NO2(-). Described herein is the preparation, structural and electronic properties of these manganese complexes.
