Cubic coordination polyhedra of uranium (dark purple polyhedra) in different compounds: (a) bulk UO2 (Cooper, 1982), (b) the {U38} cluster (Falaise et al., 2013c), and (c) the {U13} cluster (I). The structure of I is drawn as [U13(μ4-Ooxo)8Cl6(MeO)32] in order to omit the disorder between chloride and methoxide anions for clarity. Colour code: carbon, black; oxygen, red; chlorine, light green; uranium, dark purple. Hydrogen atoms are omitted for clarity in (b) and (c). |
