Abstract

We report a new synthesis of the seleno-bis (S-glutathionyl) arsinium anion, [(GS)₂AsSe]^-. An aqueous solution of bis-glutathionylarsenous acid. (GS)₂As-OH, prepared form stoichiometric glutathione and arsenite, was reacted in situ with a solution of sodium hydrogen selenide, prepared from elemental selenium and sodium borohydride. Analysis of the arsenic and selenium K-edge X-ray absorption spectra indicated virtually quantitative formation of [(GS)₂AsSe]^- with As Se and As-S distances of 2.31 and 2.25 Å, respectively, and the concentrated sample allowed a definitive X-ray spectroscopic characterization. Size-exclusion chromatography was used to separate [(GS)₂AsSe]- from residual borate in the reaction mixture.
