I am ligand : A pentadentate bispidine ligand with two tertiary amine and three pyridine donors stabilizes the uncommon intermediate‐spin electronic configuration of Co III ( S =1; see picture: C gray, N blue, O red, Co violet). Dissociation of the monodentate coligand yields a catalytically active pentacoordinate complex.
