Materials Data on HoPbAu by Materials Project
HoAuPb is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Ho is bonded to four equivalent Au and six equivalent Pb atoms to form a mixture of distorted corner and face-sharing HoPb6Au4 tetrahedra. All Ho–Au bond lengths are 2.96 Å. All Ho–Pb bond lengths are 3.42 Å. Au is bonded in a body-centered cubic geometry to four equivalent Ho and four equivalent Pb atoms. All Au–Pb bond lengths are 2.96 Å. Pb is bonded in a distorted q6 geometry to six equivalent Ho and four equivalent Au atoms.
