K. Takao and Y. Ikeda

Abstract: In the title compound, [U(C₄F₉O₃S)O₂(C₄H₈O)₃], each U^VI ion is located on a twofold rotation axis and is seven-coordinated by two terminal O atoms in the axial positions [U-O = 1.737 (5) Å] and five O atoms from two monodentate nonafluorobutanesulfonate (NfO^-) and three tetrahydrofuran ligands in the equatorial plane [U-O = 2.388 (5)-2.411 (4) Å] in a pentagonal-bipyramidal geometry. The crystal packing exhibits weak intermolecular C-HO hydrogen bonds involving the non-coordinated O atoms of the NfO^- ligands.
