description: U3(Mo5O16)4 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent U sites. In the first U site, U is bonded in a distorted linear geometry to eight O atoms. There are a spread of U–O bond distances ranging from 1.80–2.64 Å. In the second U site, U is bonded to eight O atoms to form UO8 hexagonal bipyramids that share corners with two equivalent UO8 hexagonal bipyramids and edges with three MoO6 octahedra. There are a spread of U–O bond distances ranging from 2.05–2.45 Å. There are six inequivalent Mo sites. In the first Mo site, Mo is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Mo–O bond distances ranging from 1.75–2.38 Å. In the second Mo site, Mo is bonded to six O atoms to form distorted corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles are 22°. There are a spread of Mo–O bond distances ranging from 1.74–2.33 Å. In the third Mo site, Mo is bonded to six O atoms to form distorted MoO6 octahedra that share a cornercorner with one MoO6 octahedra and an edgeedge with one UO8 hexagonal bipyramid.
