Materials Data on HfBiRh by Materials Project

Abstract

HfRhBi is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Hf is bonded in a body-centered cubic geometry to four equivalent Rh and four equivalent Bi atoms. All Hf–Rh bond lengths are 2.86 Å. All Hf–Bi bond lengths are 2.86 Å. Rh is bonded to four equivalent Hf atoms to form distorted RhHf4 tetrahedra that share corners with four equivalent BiHf4 tetrahedra, corners with twelve equivalent RhHf4 tetrahedra, and edges with six equivalent BiHf4 tetrahedra. Bi is bonded to four equivalent Hf atoms to form distorted BiHf4 tetrahedra that share corners with four equivalent RhHf4 tetrahedra, corners with twelve equivalent BiHf4 tetrahedra, and edges with six equivalent RhHf4 tetrahedra.
