Bi2O5 crystallizes in the orthorhombic Cmcm space group. Bi(1) is bonded to one O(1), two equivalent O(2), and three equivalent O(3) atoms to form a mixture of corner and edge-sharing BiO6 octahedra. The corner-sharing octahedral tilt angles range from 32-49°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent Bi(1) atoms. In the second O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Bi(1) atoms. In the third O site, O(2) is bonded in a water-like geometry to two equivalent Bi(1) atoms.

The corner-sharing octahedral tilt angles range from 32-49°. The Bi(1)-O(1) bond length is 2.11 Å. There is one shorter (2.13 Å) and one longer (2.14 Å) Bi(1)-O(2) bond length. All Bi(1)-O(3) bond lengths are 2.22 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent Bi(1) atoms. In the second O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Bi(1) atoms.
