Materials Data on V2B3 by Materials Project
V2B3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent V+4.50+ sites. In the first V+4.50+ site, V+4.50+ is bonded to twelve B3- atoms to form a mixture of edge and face-sharing VB12 cuboctahedra. There are a spread of V–B bond distances ranging from 2.30–2.36 Å. In the second V+4.50+ site, V+4.50+ is bonded in a 7-coordinate geometry to seven B3- atoms. There are a spread of V–B bond distances ranging from 2.21–2.32 Å. There are three inequivalent B3- sites. In the first B3- site, B3- is bonded in a 9-coordinate geometry to six equivalent V+4.50+ and three B3- atoms. There is two shorter (1.72 Å) and one longer (1.73 Å) B–B bond length. In the second B3- site, B3- is bonded in a 9-coordinate geometry to six V+4.50+ and three B3- atoms. Both B–B bond lengths are 1.76 Å. In the third B3- site, B3- is bonded in a 9-coordinate geometry to seven V+4.50+ and two equivalent B3- atoms.
