Ti2Al is half-Heusler-derived structured and crystallizes in the cubic F-43m space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a body-centered cubic geometry to four equivalent Ti(2) and four equivalent Al(1) atoms. In the second Ti site, Ti(2) is bonded in a 10-coordinate geometry to four equivalent Ti(1) and six equivalent Al(1) atoms. Al(1) is bonded in a 10-coordinate geometry to four equivalent Ti(1) and six equivalent Ti(2) atoms.
