Materials Data on TiAlPt by Materials Project
PtTiAl crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ti is bonded in a 6-coordinate geometry to two equivalent Ti, six equivalent Pt, and six equivalent Al atoms. Both Ti–Ti bond lengths are 2.71 Å. All Ti–Pt bond lengths are 2.90 Å. All Ti–Al bond lengths are 2.90 Å. Pt is bonded in a 11-coordinate geometry to six equivalent Ti and five equivalent Al atoms. There are three shorter (2.57 Å) and two longer (2.71 Å) Pt–Al bond lengths. Al is bonded to six equivalent Ti and five equivalent Pt atoms to form a mixture of distorted corner and face-sharing AlTi6Pt5 trigonal bipyramids.
