The material structure described by UW3O11 crystallizes in the orthorhombic Pmma space group. U(1) is bonded to one O(6), two equivalent O(1), and four equivalent O(7) atoms to form distorted UO7 pentagonal bipyramids that share corners with two equivalent W(2)O6 octahedra, corners with two equivalent U(1)O7 pentagonal bipyramids, edges with two equivalent W(2)O6 octahedra, and edges with two equivalent U(1)O7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 39°. There are two inequivalent W sites. In the first W site, W(1) is bonded to two equivalent O(2), two equivalent O(5), and two equivalent O(8) atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 0-19°. In the second W site, W(2) is bonded to one O(4), one O(6), one O(7), one O(8), and two equivalent O(3) atoms to form WO6 octahedra that share  a cornercorner with one W(1)O6 octahedra, corners with four equivalent W(2)O6 octahedra,  a cornercorner with one U(1)O7 pentagonal bipyramid, and  an edgeedge with one U(1)O7 pentagonal bipyramid. The corner-sharing octahedral tilt angles range from 3-32°. There are nine inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent U(1) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent W(1) atoms. In the third O site, O(2) is bonded in a linear geometry to two equivalent W(1) atoms. In the fourth O site, O(3) is bonded in a linear geometry to two equivalent W(2) atoms. In the fifth O site, O(4) is bonded in a linear geometry to two equivalent W(2) atoms. In the sixth O site, O(5) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. In the seventh O site, O(6) is bonded in a 3-coordinate geometry to one U(1) and two equivalent W(2) atoms. In the eighth O site, O(7) is bonded in a distorted trigonal planar geometry to two equivalent U(1) and one W(2) atom. In the ninth O site, O(8) is bonded in a bent 150 degrees geometry to one W(1) and one W(2) atom. is represented by the CIF file [CIF]
