Isolation of a Uranyl [UO₂]⁺ Species: Crystallographic Comparison of the Dioxouranium(<scp>V</scp>) and (<scp>VI</scp>) Compounds [UO₂(OPPh₃)₄](OTf)<i>_n</i> (<i>n</i>=1, 2)

Abstract

Variations in the structural parameters of the analogous [UO2]2+ and [UO2]+ compounds, [UO2(OPPh3)4](OTf)n (n=1, 2; picture shows the cation of the n=1 complex), allow a direct comparison of the observed data with that obtained from EXAFS studies in solution, and from theoretical studies.
