Stereoselectivity and exciton cotton effects in mixed complexes of zinc(II)

Abstract

Mixed complexes of Zn(II) with chiral aminoacids and 1,10-phenanthroline have been prepared and their C.D. and O.R.D. spectra measured. All the C.D. spectra exhibited an exciton splitting at 268 nm and their intensities depended on the chiral ligand. These results were interpreted in terms of steric effects through the exciton theory.
