(WO3)4H2 crystallizes in the triclinic P1 space group. The structure consists of one 1333-74-0 atom inside a WO3 framework. In the WO3 framework, there are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 7-15°. In the second W site, W(2) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 7-15°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one W(1) and one W(2) atom. In the second O site, O(2) is bonded in a linear geometry to one W(1) and one W(2) atom. In the third O site, O(3) is bonded in a linear geometry to one W(1) and one W(2) atom. In the fourth O site, O(4) is bonded in a linear geometry to one W(1) and one W(2) atom. 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 linear geometry to one W(1) and one W(2) atom.
