Materials Data on CsU2O6 by Materials Project
CsU2O6 crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Cs1+ is bonded to six equivalent O2- atoms to form CsO6 octahedra that share corners with twelve equivalent UO6 octahedra. The corner-sharing octahedral tilt angles are 70°. All Cs–O bond lengths are 3.48 Å. U+5.50+ is bonded to six equivalent O2- atoms to form UO6 octahedra that share corners with six equivalent CsO6 octahedra and corners with six equivalent UO6 octahedra. The corner-sharing octahedra tilt angles range from 41–70°. All U–O bond lengths are 2.12 Å. O2- is bonded in a distorted bent 150 degrees geometry to one Cs1+ and two equivalent U+5.50+ atoms.
