Stereospecific ligands and their complexes. Part XXI. Synthesis, characterization, circular dichroism and antimicrobial activity of cobalt(III) complexes with some edda-type of ligands. Crystal structure of potassium-Δ-(−)589-s-cis-oxalato-(S,S)-ethyle

The Δ absolute configurations of the isolated complexes have been predicted on the basis of their circular dichroism (CD) spectra and it was confirmed by single-crystal X-ray analysis of K-Δ-(−)589-s-cis-[Co(S,S-eddp)(ox)]·0.5H2O.
