[Co(<I>R</I>,<I>S</I>-sexidentate-<I>N</I><SUB>2</SUB>,<I>S</I><SUB>2</SUB>,<I>O</I><SUB>2</SUB>)] and [Co(<I>R</I>-terdentate-<I>N</I>,<I>S</I>,<I>O</I>)(<I>S</I>-<I>terdentate</I>-<I>N</I>,<I>S</I>,<I>O</I>)] type complexes, including the title complex cation, [Co(<I>R</I>,<I>S</I>-ebp)]<SUP>+</SUP>, were prepared and resolved. The crystal structure and absolute configuration of the (+)<SUB>560</SUB><SUP>CD</SUP>-[Co(<I>R</I>,<I>S</I>-ebp)]<SUP>+</SUP> isomer were determined by X-ray diffraction. The complex cation has an [<I>S</I>] configuration. The <I>R</I>,<I>S</I>-ebp coordinates as a sexidentate, of which two sulfur donor atoms take selectively <I>R</I>(<I>S</I>). The absorption and CD spectra are discussed in comparison with those of the related complexes.
