UTi2O6 crystallizes in the monoclinic C2/m space group. U(1) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form distorted UO6 octahedra that share corners with eight equivalent Ti(1)O6 octahedra and edges with two equivalent U(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-63°. Ti(1) is bonded to one O(2), two equivalent O(3), and three equivalent O(1) atoms to form TiO6 octahedra that share corners with two equivalent Ti(1)O6 octahedra, corners with four equivalent U(1)O6 octahedra, and edges with three equivalent Ti(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 28-63°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to three equivalent Ti(1) atoms. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to two equivalent U(1) and one Ti(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one U(1) and two equivalent Ti(1) atoms.

The corner-sharing octahedral tilt angles range from 40-63°. Both U(1)-O(3) bond lengths are 2.23 Å. All U(1)-O(2) bond lengths are 2.30 Å. Ti(1) is bonded to one O(2), two equivalent O(3), and three equivalent O(1) atoms to form TiO6 octahedra that share corners with two equivalent Ti(1)O6 octahedra, corners with four equivalent U(1)O6 octahedra, and edges with three equivalent Ti(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 28-63°. The Ti(1)-O(2) bond length is 1.87 Å. There is one shorter (1.87 Å) and one longer (2.08 Å) Ti(1)-O(3) bond length. There are two shorter (1.95 Å) and one longer (2.10 Å) Ti(1)-O(1) bond length. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to three equivalent Ti(1) atoms.
