W3O10 crystallizes in the orthorhombic Fmm2 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 0-29°. In the second W site, W(2) is bonded to one O(4), one O(5), and four equivalent O(2) atoms to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 29°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one W(1) and one W(2) atom. In the third O site, O(3) is bonded in a linear geometry to two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a single-bond geometry to one W(2) atom. In the fifth O site, O(5) is bonded in a single-bond geometry to one W(2) atom.

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 0-29°. Both W(1)-O(1) bond lengths are 1.93 Å. Both W(1)-O(2) bond lengths are 1.94 Å. There is one shorter (1.86 Å) and one longer (2.03 Å) W(1)-O(3) bond length. In the second W site, W(2) is bonded to one O(4), one O(5), and four equivalent O(2) atoms to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 29°. The W(2)-O(4) bond length is 2.25 Å. The W(2)-O(5) bond length is 1.74 Å. All W(2)-O(2) bond lengths are 1.95 Å. There are five inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one W(1) and one W(2) atom.
