The structure described by WO3 crystallizes in the hexagonal P6_3cm space group. W(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 1-30°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a linear geometry to two equivalent W(1) atoms. In the second O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. is represented by the CIF card [CIF]
