The compound described by WO3 crystallizes in the orthorhombic Pmma 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 0-13°. 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]
