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

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 [SO42-]total/U(VI) solutions. With increasing [SO42-]total/U(VI) ratio, bidentate coordination with a U-Sbid d...

Zusammenfassung: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 [SO42-]total/U(VI) solutions. With increasing [SO42-]total/U(VI) ratio, bidentate coordination with a U-Sbid distance of 3.11+/-0.02 A becomes dominant.
