description: UMo2O8 crystallizes in the trigonal P3 space group. The structure is three-dimensional. there are five inequivalent U4+ sites. In the first U4+ site, U4+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of U–O bond distances ranging from 2.31–2.50 Å. In the second U4+ site, U4+ is bonded to six O2- atoms to form UO6 octahedra that share corners with six MoO4 tetrahedra. There are three shorter (2.20 Å) and three longer (2.21 Å) U–O bond lengths. In the third U4+ site, U4+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of U–O bond distances ranging from 2.34–2.45 Å.
