Materials Data on V8O by Materials Project
V8O crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. there are three inequivalent V sites. In the first V site, V is bonded in a distorted body-centered cubic geometry to eight V atoms. There are a spread of V–V bond distances ranging from 2.54–2.70 Å. In the second V site, V is bonded in a single-bond geometry to four equivalent V and one O atom. The V–O bond length is 1.95 Å. In the third V site, V is bonded in an L-shaped geometry to four equivalent V and two equivalent O atoms. Both V–O bond lengths are 2.13 Å. O is bonded to six V atoms to form edge-sharing OV6 octahedra.
