Title: The Structure of Uranyl Sulfate in Aqueous Solution - Monodentate Versus Bidentate Coordination

Abstract

The structure of U(VI) aquo sulfato complexes has been investigated by LIII-edge EXAFS spectroscopy. A monodentate coordination with a U-Smon distance of 3.57{+-}0.02 A prevails in equimolar [SO{sub 4}{sup 2-}]{sub total}/U(VI) solutions. With increasing [SO{sub 4}{sup 2-}]{sub total}/U(VI) ratio, bidentate coordination with a U-Sbid distance of 3.11{+-}0.02 A becomes dominant.
