The structures of (R,S)-and (RR)-(saJen)manganese(III) complexes [(R,S)-2a,b and (R,R)-2a,b] possessing axial chirality as one of their two chiral elements were unambiguously determined by X-ray crystallographic analysis. The basal salen ligands of the complexes were demonstrated to adopt a stepped
