NbO2 is trigonal omega-like structured and crystallizes in the tetragonal I4_1/amd space group. Nb(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles are 3°. O(1) is bonded in a T-shaped geometry to three equivalent Nb(1) atoms.

Nb(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles are 3°. There are four shorter (2.03 Å) and two longer (2.17 Å) Nb(1)-O(1) bond lengths. O(1) is bonded in a T-shaped geometry to three equivalent Nb(1) atoms.
