VIBRATIONAL CIRCULAR DICHROISM OF TRANSITION METAL COMPLEXES OF ACHIRAL AMINO ACIDS AND ETHYLENEDIAMINE

Abstract

We have synthesized several dissymmetric transition metal complexes of Co(III) and Cr(III) using the achiral molecules, glycine, $\beta$-alanine and ethylenediamine, as bidentate ligands. Spectra have been recorded in the N-H and C-H stretching regions. In all cases the N-H signals are more intense than the C-H. We will compare their spectra with those of similar complexes in which the metal ion is coordinated to the chiral amino acid, L-alanine.
