The compound described by WO3 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(5), one O(6), two equivalent O(2), and two equivalent O(4) atoms to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 14-23°. In the second W site, W(2) is bonded to one O(5), one O(6), two equivalent O(1), and two equivalent O(3) atoms to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 14-23°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to two equivalent W(2) atoms. In the second O site, O(2) is bonded in a distorted linear geometry to two equivalent W(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent W(2) atoms. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. In the fifth O site, O(5) is bonded in a linear geometry to one W(1) and one W(2) atom. In the sixth O site, O(6) 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]
