Abstract

A stable sulfonato complex, (2-aminoethanesulfonato-N,O)bis(ethylenediamine-N,N′)cobalt(III) perchlorate, [Co(C₂H₆NO₃S)(C₂H₈N ₂)₂](ClO₄)₂, was prepared by oxidation of [Co{OS(O)CH₂CH₂NH₂-N,O}(en)₂] ²⁺ (en = NH₂CH₂CH₂NH₂) in acid media. This sulfonato complex was resolved by SP-Sephadex column chromatography and the absolute configuration of the slower eluted (-)₅₈₉-isomer was determined by X-ray analysis to be Δ.
