Materials Data on V5Sb4 by Materials Project
V5Sb4 is Titanium telluride structured and crystallizes in the tetragonal I4/m space group. The structure is three-dimensional. there are two inequivalent V+2.40+ sites. In the first V+2.40+ site, V+2.40+ is bonded in a square co-planar geometry to four equivalent Sb3- atoms. All V–Sb bond lengths are 2.94 Å. In the second V+2.40+ site, V+2.40+ is bonded to five equivalent Sb3- atoms to form a mixture of corner and edge-sharing VSb5 square pyramids. There are a spread of V–Sb bond distances ranging from 2.68–2.72 Å. Sb3- is bonded in a 6-coordinate geometry to six V+2.40+ atoms.
