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