Materials Data on VGeRh by Materials Project

Abstract

VRhGe is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. V is bonded in a body-centered cubic geometry to four equivalent Rh and four equivalent Ge atoms. All V–Rh bond lengths are 2.51 Å. All V–Ge bond lengths are 2.51 Å. Rh is bonded to four equivalent V and six equivalent Ge atoms to form distorted RhV4Ge6 tetrahedra that share corners with four equivalent GeV4Rh6 tetrahedra, corners with six equivalent RhV4Ge6 tetrahedra, edges with six equivalent GeV4Rh6 tetrahedra, and faces with twelve equivalent RhV4Ge6 tetrahedra. All Rh–Ge bond lengths are 2.90 Å. Ge is bonded to four equivalent V and six equivalent Rh atoms to form distorted GeV4Rh6 tetrahedra that share corners with four equivalent RhV4Ge6 tetrahedra, corners with six equivalent GeV4Rh6 tetrahedra, edges with six equivalent RhV4Ge6 tetrahedra, and faces with twelve equivalent GeV4Rh6 tetrahedra.
