NbO3 is alpha Rhenium trioxide structured and crystallizes in the tetragonal P4mm space group. Nb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles range from 0-5°. There are two 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.

Nb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles range from 0-5°. There is one shorter (1.94 Å) and one longer (2.07 Å) Nb(1)-O(2) bond length. All Nb(1)-O(1) bond lengths are 1.99 Å. There are two 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.
