Abstract: The coordination of the stereoisomeric chelating ligands is utilized as an alternative way how to obtain selective analytical titration agents. A nucleophilic addition of ethylenediamine on sodium maleate yielded a mixture of stereoisomers of ethylenediamine-N,N'-disuccinic acid from which the meso and гас forms were successfully separated via their copper(II) complexes. The obtained compounds were characterized by their i.r. spectra. From the crystallographic measurements it was unambiguously determined which of the isolated forms is the racemic modification.
