Materials Data on VO2 by Materials Project
VO2 is Rutile structured and crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. V4+ is bonded to six equivalent O2- atoms to form a mixture of corner and edge-sharing VO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There is two shorter (1.91 Å) and four longer (1.99 Å) V–O bond length. O2- is bonded in a distorted trigonal planar geometry to three equivalent V4+ atoms.
