Materials Data on ErPbAu by Materials Project
ErAuPb is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Er is bonded to four equivalent Au and six equivalent Pb atoms to form a mixture of distorted corner and face-sharing ErPb6Au4 tetrahedra. All Er–Au bond lengths are 2.95 Å. All Er–Pb bond lengths are 3.41 Å. Au is bonded in a body-centered cubic geometry to four equivalent Er and four equivalent Pb atoms. All Au–Pb bond lengths are 2.95 Å. Pb is bonded in a distorted q6 geometry to six equivalent Er and four equivalent Au atoms.
