Materials Data on TaGaPt by Materials Project
TaPtGa is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Ta is bonded in a body-centered cubic geometry to four equivalent Pt and four equivalent Ga atoms. All Ta–Pt bond lengths are 2.66 Å. All Ta–Ga bond lengths are 2.66 Å. Pt is bonded to four equivalent Ta and six equivalent Ga atoms to form a mixture of distorted corner and face-sharing PtTa4Ga6 tetrahedra. All Pt–Ga bond lengths are 3.07 Å. Ga is bonded in a 4-coordinate geometry to four equivalent Ta and six equivalent Pt atoms.
