Nb2O5 crystallizes in the monoclinic C2/m space group. Nb(1) is bonded to one O(2), two equivalent O(1), and three equivalent O(3) atoms to form a mixture of distorted corner and edge-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles range from 0-33°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent Nb(1) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent Nb(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Nb(1) atoms.

The corner-sharing octahedral tilt angles range from 0-33°. The Nb(1)-O(2) bond length is 1.92 Å. There is one shorter (1.80 Å) and one longer (2.22 Å) Nb(1)-O(1) bond length. There are two shorter (2.01 Å) and one longer (2.21 Å) Nb(1)-O(3) bond length. There are three inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent Nb(1) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent Nb(1) atoms.
