Abstract

A stable sulfonato complex, [Co{OS(O)₂CH₂CH₂NH₂-O,N}(en) ₂]²⁺, was prepared upon oxidation of [Co{OS(O)-CH₂CH₂NH₂-O,N} (en)₂]²⁺ in acid media. This sulfonato complex was resolved by SP-Sephadex column chromatography (eluent: 0.1 mol dm^-3 Na₂[Sb₂{(+)-tartrate}₂]). The absolute configuration of the slower eluted (-)₅₈₉-isomer was determined to be Δ by the X-ray method.
