Abstract
Stereoisomeric Tc(V) complexes derived from meso and racemic 2,3-dimercaptosuccinic acid dimethylester have been identified by 1H NMR spectroscopy and some of them have been isolated. In methanolic amine or potassium hydroxide solution, complexes of the meso ligand racemize to give the complex compounds of the racemic 2,3-dimercaptosuccinic acid dimethylester. In methanolic potassium hydroxide solution, Tc(V) complexes of racemic 2,3-dimercaptosuccinic acid are formed by ester hydrolysis.
