W2O5 crystallizes in the orthorhombic Pba2 space group. W(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form corner-sharing WO5 trigonal bipyramids. There are three inequivalent O sites. In the first O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. In the second O site, O(1) is bonded in a bent 150 degrees 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.

The W(1)-O(3) bond length is 1.93 Å. There is one shorter (1.90 Å) and one longer (1.99 Å) W(1)-O(1) bond length. There is one shorter (1.85 Å) and one longer (2.08 Å) W(1)-O(2) bond length.
