Materials Data on YPbAu by Materials Project
YAuPb is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Y is bonded to four equivalent Au and six equivalent Pb atoms to form a mixture of distorted corner and face-sharing YPb6Au4 tetrahedra. All Y–Au bond lengths are 2.97 Å. All Y–Pb bond lengths are 3.43 Å. Au is bonded in a body-centered cubic geometry to four equivalent Y and four equivalent Pb atoms. All Au–Pb bond lengths are 2.97 Å. Pb is bonded in a distorted q6 geometry to six equivalent Y and four equivalent Au atoms.
