• Circular dichroism (CD) and proton magnetic resonance (PMR) spectra of nickel(II) complexes containing a series of ethylenediamine-<I>N</I>,<I>N</I>′-diacetic acid (H<SUB>2</SUB>edda)-type optically active quadridentate ligands were measured in aqueous solutions. The epro complex which is an edda-type optically active ligand containing L-proline residues is found to exhibit the same CD spectrum as complexes of other edda-type ligands containing L-alanine, L-valine, L-phenylalanine, and L-serine residues. The CD and PMR spectra of the mixed complexes of these edda-type ligands having an oxalate ion was also measured. From the CD and PMR spectral data, it is concluded that these complexes stereospecifically take the <I>Δ</I>-<I>s</I>-<I>cis</I> form in solution. The large contact shift observed for the a protons of the amino acidate moieties indicates that the substituent groups become axial to the chelate plane.
