The structure described by WO3 crystallizes in the tetragonal P-42_1m space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to two equivalent O(1) and four equivalent O(4) atoms to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 0-27°. In the second W site, W(2) is bonded to one O(3), one O(4), two equivalent O(2), and two equivalent O(5) atoms to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 0-31°. There are five inequivalent O sites. In the first O site, O(5) is bonded in a linear geometry to two equivalent W(2) atoms. In the second O site, O(1) 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(2) atoms. In the fourth O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent W(2) atoms. In the fifth O site, O(4) is bonded in a bent 150 degrees geometry to one W(1) and one W(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
