The material described by V8O crystallizes in the tetragonal P4_2/mnm space group. There are three inequivalent V sites. In the first V site, V(1) is bonded in a distorted body-centered cubic geometry to two equivalent V(2), two equivalent V(3), and four equivalent V(1) atoms. In the second V site, V(2) is bonded in a single-bond geometry to four equivalent V(1) and one O(1) atom. In the third V site, V(3) is bonded in an L-shaped geometry to four equivalent V(1) and two equivalent O(1) atoms. O(1) is bonded to two equivalent V(2) and four equivalent V(3) atoms to form edge-sharing OV6 octahedra. is represented by the Crystallographic Information File (CIF) [CIF]
