The crystal structure described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
