The structure described by WO3 crystallizes in the monoclinic P2_1/c space group. W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 1-12°. There are three 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. In the third O site, O(3) is bonded in a linear geometry to two equivalent W(1) atoms. is represented by the CIF card [CIF]
