WO3 is alpha Rhenium trioxide-like structured and crystallizes in the orthorhombic Cmcm space group. W(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 0-5°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent W(1) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent W(1) atoms.

W(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 0-5°. Both W(1)-O(1) bond lengths are 1.93 Å. There are two shorter (1.87 Å) and two longer (2.01 Å) W(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent W(1) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent W(1) atoms.
