Materials Data on TbPbAu by Materials Project
TbAuPb is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Tb is bonded to four equivalent Au and six equivalent Pb atoms to form a mixture of distorted face and corner-sharing TbPb6Au4 tetrahedra. All Tb–Au bond lengths are 2.97 Å. All Tb–Pb bond lengths are 3.43 Å. Au is bonded in a body-centered cubic geometry to four equivalent Tb 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 Tb and four equivalent Au atoms.
