Materials Data on TiNiSb by Materials Project
NiTiSb is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Ti2+ is bonded in a 6-coordinate geometry to six equivalent Sb3- atoms. All Ti–Sb bond lengths are 2.97 Å. Ni1+ is bonded to four equivalent Sb3- atoms to form distorted corner-sharing NiSb4 tetrahedra. All Ni–Sb bond lengths are 2.57 Å. Sb3- is bonded in a 10-coordinate geometry to six equivalent Ti2+ and four equivalent Ni1+ atoms.
