U4BiO10 is Fluorite-derived structured and crystallizes in the tetragonal I4/m space group. U(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Bi(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent U(1) and one Bi(1) atom to form OU3Bi tetrahedra that share corners with four equivalent O(2)U4 tetrahedra, corners with twelve equivalent O(1)U3Bi tetrahedra,  an edgeedge with one O(2)U4 tetrahedra, and edges with five equivalent O(1)U3Bi tetrahedra. In the second O site, O(2) is bonded to four equivalent U(1) atoms to form OU4 tetrahedra that share corners with sixteen equivalent O(1)U3Bi tetrahedra, edges with two equivalent O(2)U4 tetrahedra, and edges with four equivalent O(1)U3Bi tetrahedra.
U4BiO10 is Fluorite-derived structured and crystallizes in the tetragonal I4/m space group. U(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Both U(1)-O(2) bond lengths are 2.35 Å. There are a spread of U(1)-O(1) bond distances ranging from 2.32-2.35 Å. Bi(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. All Bi(1)-O(1) bond lengths are 2.43 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent U(1) and one Bi(1) atom to form OU3Bi tetrahedra that share corners with four equivalent O(2)U4 tetrahedra, corners with twelve equivalent O(1)U3Bi tetrahedra,  an edgeedge with one O(2)U4 tetrahedra, and edges with five equivalent O(1)U3Bi tetrahedra. In the second O site, O(2) is bonded to four equivalent U(1) atoms to form OU4 tetrahedra that share corners with sixteen equivalent O(1)U3Bi tetrahedra, edges with two equivalent O(2)U4 tetrahedra, and edges with four equivalent O(1)U3Bi tetrahedra.
