Materials Data on HfGePt by Materials Project

Abstract

HfPtGe 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 Pt and four equivalent Ge atoms. All Hf–Pt bond lengths are 2.72 Å. All Hf–Ge bond lengths are 2.72 Å. Pt is bonded to four equivalent Hf atoms to form distorted PtHf4 tetrahedra that share corners with four equivalent GeHf4 tetrahedra, corners with twelve equivalent PtHf4 tetrahedra, and edges with six equivalent GeHf4 tetrahedra. Ge is bonded to four equivalent Hf atoms to form distorted GeHf4 tetrahedra that share corners with four equivalent PtHf4 tetrahedra, corners with twelve equivalent GeHf4 tetrahedra, and edges with six equivalent PtHf4 tetrahedra.
