Materials Data on TaPbBr by Materials Project
TaPbBr is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Ta is bonded to six equivalent Pb and four equivalent Br atoms to form a mixture of distorted corner and face-sharing TaPb6Br4 tetrahedra. All Ta–Pb bond lengths are 3.39 Å. All Ta–Br bond lengths are 2.94 Å. Pb is bonded in a 4-coordinate geometry to six equivalent Ta and four equivalent Br atoms. All Pb–Br bond lengths are 2.94 Å. Br is bonded in a body-centered cubic geometry to four equivalent Ta and four equivalent Pb atoms.
