L-Argininium tris(acetato-O,O')dioxouranium(III)–acetic acid–water (1/1/1)

Abstract

The uranyl ion in the title compound, (C 6 H 15 N 4 O 2 )[UO 2 (C 2 H 3 O 2 ) 3 ].C 2 H 4 O 2 .H 2 O, is sixfold coordinated by three bidentate acetic acid ions. The O atoms form a hexagonal bipyramidal arrangement around the U atom. The non-crystallographic symmetry of the cation is approximately D 6h . The cation is a positively charged zwitterion. The side chain of the amino acid has a conformation where the C γ atom is in a staggered trans position relative to the carboxyl group. An intricate three-dimensional network of hydrogen bonds interlinks the ions and the solvent molecules.
