The material structure described by WO3 crystallizes in the triclinic P-1 space group. There are four inequivalent W sites. In the first W site, W(1) is bonded to one O(11), one O(12), one O(2), one O(3), one O(6), and one O(7) atom to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 14-22°. In the second W site, W(2) is bonded to one O(1), one O(11), one O(12), one O(4), one O(5), and one O(8) atom to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 14-24°. In the third W site, W(3) is bonded to one O(10), one O(2), one O(3), one O(6), one O(7), and one O(9) atom to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 14-22°. In the fourth W site, W(4) is bonded to one O(1), one O(10), one O(4), one O(5), one O(8), and one O(9) atom to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 14-24°. There are twelve inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one W(2) and one W(4) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one W(1) and one W(3) atom.

In the ninth O site, O(9) is bonded in a linear geometry to one W(3) and one W(4) atom. In the tenth O site, O(10) is bonded in a bent 150 degrees geometry to one W(3) and one W(4) atom.
