carboxylato)cobalt(III) complexes were prepared and characterized, where the α-amino carboxylate ligand is glycinate, (R)- or (S)-alaninate, (R)- or (S)-valinate, sarcosinate, N-ethylglycinate, (R)-prolinate, or (S)-pipecolate ((S)-2-piperidinecarboxylate). Of the three possible isomers, only the Λ-uns-mer form was prepared for each of the complexes except for the glycinato complex. The (R)-prolinato

Glycinato, L-alaninato, ethylenediamine, N,N-dimethylethylenediamine, (R)-propylenediamine, (R,R)-1,2-cyclohexanediamine and meso-2,3-butanediamine cobalt(III) complexes of a tripodlike ligand, N-(2-aminoethyl)iminodiacetate have been prepared. The geometrical configurations are assigned on the basis of their absorption, circulardichroism, and 1H-NMR spectra. The trans(O) isomer of meso-2,3-butanediamine
