description: VO2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are twelve inequivalent V4+ sites. In the first V4+ site, V4+ is bonded to six O2- atoms to form VO6 octahedra that share a cornercorner with one VO4 tetrahedra and edges with five VO6 octahedra. There are a spread of V–O bond distances ranging from 1.83–2.18 Å. In the second V4+ site, V4+ is bonded to six O2- atoms to form edge-sharing VO6 octahedra. There are a spread of V–O bond distances ranging from 1.92–2.03 Å. In the third V4+ site, V4+ is bonded to six O2- atoms to form edge-sharing VO6 octahedra. There are a spread of V–O bond distances ranging from 1.81–2.02 Å. In the fourth V4+ site, V4+ is bonded to six O2- atoms to form distorted VO6 octahedra that share a cornercorner with one VO4 tetrahedra and edges with five VO6 octahedra.
