Crystal structure of the sodium salt of the uranyl-oxyacetate-fluoride dimer, Na4(UO2)2(OCH2COO)2F 4 · 6H2O

• The structure of the ternary uranyl-oxyacetate-fluoride dimer, (UO2)2(OCH2COO)2F4 4-, was studied by single crystal X-ray diffraction. The space group is P1̄, and the structure contains discrete dimers with a double pentagonal bipyramid geometry, linked by octahedrally coordinated sodium ions. The uranyl ion has a coordination number of five with two fluorides and three oxygens coordinated in a plane perpendicular to the linear UO2 axis. The dimer is formed via bridging oxygen atoms from the deprotonated hydroxyl groups of the glycolate ligands.
