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 are formed stereospecifically. VIS., CD.‐ and NMR.‐spectra are reported and a proposal is given for the absolute configuration of all the compounds isolated.
