Circular Dichroism of Cobalt(III) Complexes of Optically Active Amino Acids
O’BRIEN and TOOLE (1) studied theoptical rotatory dispersion (ORD) of complexes formed by several colorless metal ions with optically active amines. They concluded that the effects were independent of the nature of the central metal ion and of the nature of the active amines, but dependent on the number of ligand molecules coordinated. SHIMURA (2) showed that for [Co(NH3)4L-leuc] (ClO4)2 [leuc = NH2CH(CO2)C2H3 (CH3)2] the presence of the optically active ligand caused an anomalous dispersion curve in the region of the first absorption band of Co(III). The present paper reports the study of the contributions to the optical activity from the dissymmetric spiral configuration
