Materials Data on LiVSb by Materials Project
LiVSb is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Li1+ is bonded to six equivalent Sb3- atoms to form LiSb6 octahedra that share corners with six equivalent LiSb6 octahedra, corners with twelve equivalent VSb4 tetrahedra, edges with twelve equivalent LiSb6 octahedra, and faces with four equivalent VSb4 tetrahedra. The corner-sharing octahedral tilt angles are 0°. All Li–Sb bond lengths are 3.21 Å. V2+ is bonded to four equivalent Sb3- atoms to form VSb4 tetrahedra that share corners with twelve equivalent LiSb6 octahedra, corners with twelve equivalent VSb4 tetrahedra, and faces with four equivalent LiSb6 octahedra. The corner-sharing octahedral tilt angles are 55°. All V–Sb bond lengths are 2.78 Å. Sb3- is bonded in a 10-coordinate geometry to six equivalent Li1+ and four equivalent V2+ atoms.
