NbO2 is beta Vanadium nitride-like structured and crystallizes in the tetragonal I4_1/a space group. Nb(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of corner and edge-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles range from 33-58°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to three equivalent Nb(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to three equivalent Nb(1) atoms.

Nb(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of corner and edge-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles range from 33-58°. There are a spread of Nb(1)-O(1) bond distances ranging from 2.03-2.10 Å. There are a spread of Nb(1)-O(2) bond distances ranging from 1.95-2.19 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to three equivalent Nb(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to three equivalent Nb(1) atoms.
