Abstract
The species UO2(DMSO) 2+5 is shown from1H NMR studies to be the predominant dioxouranium(VI) species existing in dilute anhydrous acetonedimethyl sulfoxide (DMSO) solutions, and this result is compared with data reported for the analogous water-acetone-dimethyl sulfoxide system. Complete line-shape analyses of exchange-modified1H NMR line shapes indicate that the mechanism for DMSO exchange on UO2(DMSO) 2+5 is probably of theD orI D type. A typical set of rate parameters arek ex (260°K) =273±14 sec−1, ΔH #=38.9±0.5 kJ-mole−1, and ΔS #=−47.5±1.8 J-oK−1-mole−1 for a solution in which [UO2(DMSO)5 2+], [DMSO], and [d 6 acetone] are, respectively, 0.01155, 0.0875, and 13.00 moles-dm−3.
