Seven optically active cobalt(III) complexes of [Co(bidentate-<I>N</I>,<I>S</I> or -<I>N</I>,<I>Se</I>)(tn)<SUB>2</SUB>] type were prepared for the first time; bidentate-<I>N</I>,<I>S</I> or -<I>N</I>,<I>Se</I> denotes 2-aminoethanethiolato (aet), 2-aminoethaneselenolato (aes), 2-aminoethanesulfenato (aese), 2-aminoethanesulfinato (aesi), 2-(methylthio)ethylamine (mea), and 2-(methyl-seleno)ethylamine (mseea). These complexes were characterized from their absorption, CD, and <SUP>1</SUP>H NMR spectra. All complexes obtained were assigned to the <I>Λ</I> configuration. The (+)<SUB>550</SUB><SUP>CD</SUP> mea isomer took selectively the <I>Λ</I>-(<I>R</I>) configuration in solution, while the (+)<SUB>550</SUB><SUP>CD</SUP> mseea isomer a mixture of the <I>Λ</I>-(<I>R</I>) and <I>Λ</I>-(<I>S</I>) ones. The absorption and CD spectra of the complexes are discussed in comparison with those of the corresponding bis(ethylenediamine)cobalt(III) complexes. The <I>Λ</I>-(<I>R</I>)- and <I>Λ</I>-(<I>S</I>)-[Co(aese)(tn)<SUB>2</SUB>]<SUP>2+</SUP> isomers showed the CD spectral change with time and it was suggested that the epimerization at sulfur was accompanied by the racemization of the skew pair of chelate rings.
