WO2 is Hydrophilite-like structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form a mixture of edge and corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 45-53°. In the second W site, W(2) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form a mixture of edge and corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 45-53°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one W(1) and two equivalent W(2) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one W(1) and two equivalent W(2) atoms. In the third O site, O(3) is bonded in a 3-coordinate geometry to one W(1) and two equivalent W(2) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one W(1) and two equivalent W(2) atoms.

The corner-sharing octahedral tilt angles range from 45-53°. The W(1)-O(1) bond length is 2.10 Å. The W(1)-O(3) bond length is 2.11 Å. Both W(1)-O(2) bond lengths are 2.05 Å. Both W(1)-O(4) bond lengths are 2.09 Å. In the second W site, W(2) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form a mixture of edge and corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 45-53°. The W(2)-O(1) bond length is 2.10 Å. The W(2)-O(3) bond length is 2.05 Å. There is one shorter (2.05 Å) and one longer (2.15 Å) W(2)-O(2) bond length. There is one shorter (2.09 Å) and one longer (2.11 Å) W(2)-O(4) bond length. There are four inequivalent O sites.
