Materials Data on V3B2 by Materials Project
V3B2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. there are two inequivalent V2+ sites. In the first V2+ site, V2+ is bonded in a square co-planar geometry to four equivalent B3- atoms. All V–B bond lengths are 2.32 Å. In the second V2+ site, V2+ is bonded in a distorted hexagonal planar geometry to six equivalent B3- atoms. There are four shorter (2.27 Å) and two longer (2.28 Å) V–B bond lengths. B3- is bonded in a 9-coordinate geometry to eight V2+ and one B3- atom. The B–B bond length is 1.79 Å.
