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.
