The material described by W3O8 crystallizes in the monoclinic P2/c space group. There are two inequivalent W sites. In the first W site, 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 38-56°. In the second W site, W(2) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form a mixture of distorted edge and corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 38-56°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one W(1) and one W(2) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one W(1) and two equivalent W(2) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one W(1) and one W(2) atom. In the fourth O site, O(4) is bonded in a water-like geometry to two equivalent W(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
