✦ Synopsis

Abstract

The cis‐N/trans‐N interconversion of the title compound containing glycine and (R)‐ or (S)‐leucine has been studied by polarimetric and spectrophotometric techniques. Equilibrium constants were determined on the basis of kinetic and thermodynamic data. It is shown that the chirality of the bidentate amino‐acid has a pronounced influence on the cis‐trans equilibrium of these systems. Possible mechanisms of the interconversion reaction are discussed.

## Abstract The synthesis of mixed‐ligand cobalt(III) complexes with (__S__)‐aspartic‐N‐monoacetic acid ((__S__)‐AMA) and different amino‐acids Na[Co((__S__)‐AMA)(AA)] (AA = gly, (__R__)‐ and (__S__)‐ala, val, phe, ser and leu) leads to a mixture of __cis__‐N‐ and __trans__‐N‐isomers. These isomers
