The crystal structure described by WO3 is alpha Rhenium trioxide-like structured and crystallizes in the orthorhombic Pbcn space group. W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 6-7°. 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]
