(a) Molecular units in (I). Non-H atoms are represented as displacement ellipsoids drawn at 50% probability, while H atoms are represented as small spheres with arbitrary radii. Atom O8 is bonded to two H atoms, each with site occupancy 0.50; (b) and (c) coordination geometries around U2 and U1, respectively. Symmetry codes are defined in Table 2. |
