Abstract

The structure of (R,R)-(salen)manganese(III) complex (2) possessing axial chirality as a chiral element was determined unambiguously by X-ray analysis. The central manganese ion of 2 is coordinated by two aqua ligands at theapical sites. The attractive interaction between the aqua ligand and the 2"-phenyl group in the C3-naphthyl substituent affects the ligand conformation and, in turn, influences the asymmetric induction by 2.
