• Five carbonato complexes, [Co(CO<SUB>3</SUB>)(ox)(tn)]<SUP>−</SUP>, <I>cis</I>-[Co(CO<SUB>3</SUB>)(ox)(py)<SUB>2</SUB>]<SUP>−</SUP>, <I>cis</I>·<I>cis</I>-[Co(CO<SUB>3</SUB>)(NH<SUB>3</SUB>)<SUB>2</SUB>(py)<SUB>2</SUB>]<SUP>+</SUP>, <I>cis</I>-[Co(CO<SUB>3</SUB>)(en)(py)<SUB>2</SUB>]<SUP>+</SUP>, <I>cis</I>-[Co(CO<SUB>3</SUB>)(NH<SUB>3</SUB>)<SUB>2</SUB>(bpy)]<SUP>+</SUP>, and two related complexes, <I>cis</I>-[Co(ox)(NH<SUB>3</SUB>)<SUB>2</SUB>(en)]<SUP>+</SUP> and <I>cis</I>-[Co(mal)(NH<SUB>3</SUB>)<SUB>2</SUB>(en)]<SUP>+</SUP>, have been prepared and resolved. The solution CD spectra of these resolved complexes and those of diaqua complexes derived from the carbonato complexes have been measured. The CD spectral comparison in the first absorption band (T<SUB>1g</SUB>-band) region has suggested a relation in the sign of the Cotton peak between each of the carbonato complexes and the corresponding diaqua complex. Based on this relation, the assignments of the absolute configurations for the present complexes have been established.
