Materials Data on TaTiAl by Materials Project
TiAlTa is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Ti is bonded in a 4-coordinate geometry to four equivalent Ta and six equivalent Al atoms. All Ti–Ta bond lengths are 2.75 Å. All Ti–Al bond lengths are 3.17 Å. Ta is bonded in a body-centered cubic geometry to four equivalent Ti and four equivalent Al atoms. All Ta–Al bond lengths are 2.75 Å. Al is bonded to six equivalent Ti and four equivalent Ta atoms to form a mixture of distorted corner and face-sharing AlTa4Ti6 tetrahedra.
