(R)-propylenediamine cobalt(III) complexes of a tripodlike quadridentate ligand, N,N-bis(2-aminoethyl)glycinate have been prepared. The geometrical configurations are assigned on the basis of their absorption and circular dichroism spectra, 1H-NMR spectra, the elution behavior in ion-exchanger column chromatography, and the optical resolution of chiral isomers. The absolute configurations of the chiral complexes are
