Materials Data on VNiSb by Materials Project
NiVSb is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. V2+ is bonded to six equivalent Sb3- atoms to form distorted VSb6 octahedra that share corners with six equivalent VSb6 octahedra, corners with twelve equivalent NiSb4 tetrahedra, edges with twelve equivalent VSb6 octahedra, and faces with four equivalent NiSb4 tetrahedra. The corner-sharing octahedral tilt angles are 0°. All V–Sb bond lengths are 2.95 Å. Ni1+ is bonded to four equivalent Sb3- atoms to form NiSb4 tetrahedra that share corners with twelve equivalent VSb6 octahedra, corners with twelve equivalent NiSb4 tetrahedra, and faces with four equivalent VSb6 octahedra. The corner-sharing octahedral tilt angles are 55°. All Ni–Sb bond lengths are 2.56 Å. Sb3- is bonded in a 10-coordinate geometry to six equivalent V2+ and four equivalent Ni1+ atoms.
