• The [Co(O,O)<SUB>2</SUB>(N)<SUB>2</SUB>]<SUP>−</SUP>-type complexes, [Co(ox)(mal)(en)]<SUP>−</SUP>, <I>cis</I>-[Co(CO<SUB>3</SUB>)(mal)(NH<SUB>3</SUB>)<SUB>2</SUB>]<SUP>−</SUP>, <I>cis</I>-[Co(ox)(mal)(NH<SUB>3</SUB>)<SUB>2</SUB>]<SUP>−</SUP> and <I>cis</I>-[Co(mal)<SUB>2</SUB>(NH<SUB>3</SUB>)<SUB>2</SUB>]<SUP>−</SUP>, have been prepared and resolved. The CD spectra of various complexes of this type including these new complexes have been measured. The assignments of the absolute configurations have been carried out by means of the CD comparison. The CD patterns in the first absorption band region have revealed regular change with the varied O,O ligands (O,O=CO<SUB>3</SUB><SUP>2−</SUP>, ox<SUP>2−</SUP>, and mal<SUP>2−</SUP>), and from this fact a criterion for the assignments of the absolute configurations for the complexes of the present type has been established.
