The compound described by USbO5 crystallizes in the monoclinic C2/c space group. U(1) is bonded to one O(2), two equivalent O(1), and four equivalent O(3) atoms to form distorted UO7 pentagonal bipyramids that share corners with four equivalent Sb(1)O6 octahedra, edges with two equivalent Sb(1)O6 octahedra, and edges with two equivalent U(1)O7 pentagonal bipyramids. The corner-sharing octahedral tilt angles range from 2-39°. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SbO6 octahedra that share corners with two equivalent Sb(1)O6 octahedra, corners with four equivalent U(1)O7 pentagonal bipyramids, and edges with two equivalent U(1)O7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 34°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one U(1) and one Sb(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one U(1) and two equivalent Sb(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent U(1) and one Sb(1) atom. is represented by the CIF file [CIF]
