Nb2O5 crystallizes in the monoclinic C2/c space group. Nb(1) is bonded to one O(2), two equivalent O(3), and three equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles range from 27-57°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to three equivalent Nb(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Nb(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent Nb(1) atoms.

The corner-sharing octahedral tilt angles range from 27-57°. The Nb(1)-O(2) bond length is 1.93 Å. There is one shorter (1.82 Å) and one longer (2.08 Å) Nb(1)-O(3) bond length. There are a spread of Nb(1)-O(1) bond distances ranging from 1.97-2.24 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to three equivalent Nb(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Nb(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent Nb(1) atoms.
