Materials Data on V5Ge3B by Materials Project

V5BGe3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent V sites. In the first V site, V is bonded in a 8-coordinate geometry to two equivalent V and six equivalent Ge atoms. Both V–V bond lengths are 2.47 Å. All V–Ge bond lengths are 2.57 Å. In the second V site, V is bonded to two equivalent B and five equivalent Ge atoms to form a mixture of distorted corner, edge, and face-sharing VGe5B2 pentagonal bipyramids. Both V–B bond lengths are 2.18 Å. There are a spread of V–Ge bond distances ranging from 2.56–2.72 Å. B is bonded to six equivalent V atoms to form face-sharing BV6 octahedra. Ge is bonded in a 9-coordinate geometry to nine V atoms.
