Charge transfer circular dichroism of complexes of copper(II) with aminoacids and heterocyclic ligands

Abstract

In the u.v. region the C.D. spectra of mixed complexes of Cu(II), aminoacids and heterocyclic ligands depend upon the nature of the heterocyclic ligand, and work on the Cotton effects of bis-Ł-aminoacidates of cu(II) in the charge transfer region [1] has now been extended to mixed complexes of Cu(II) with an aminoacid anion and 2,2'-dipyridyl or 1,10-penanthroline. We also examined the n→n* transitions in zinc bis-L-serinate which has no charge transfer band.
