Materials Data on Ti2Al by Materials Project
Ti2Al is half-Heusler-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Ti sites. In the first Ti site, Ti is bonded in a body-centered cubic geometry to four equivalent Ti and four equivalent Al atoms. All Ti–Ti bond lengths are 2.73 Å. All Ti–Al bond lengths are 2.73 Å. In the second Ti site, Ti is bonded in a 10-coordinate geometry to four equivalent Ti and six equivalent Al atoms. All Ti–Al bond lengths are 3.15 Å. Al is bonded in a 4-coordinate geometry to ten Ti atoms.
