Materials Data on Li3YSb2 by Materials Project
Li3YSb2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four equivalent Sb3- atoms to form LiSb4 tetrahedra that share corners with three equivalent LiSb6 octahedra, corners with six equivalent YSb6 octahedra, corners with six equivalent LiSb4 tetrahedra, edges with three equivalent YSb6 octahedra, edges with three equivalent LiSb4 tetrahedra, and faces with three equivalent LiSb6 octahedra. The corner-sharing octahedra tilt angles range from 19–56°. There are three shorter (2.72 Å) and one longer (2.90 Å) Li–Sb bond lengths. In the second Li1+ site, Li1+ is bonded to six equivalent Sb3- atoms to form LiSb6 octahedra that share corners with twelve equivalent YSb6 octahedra, corners with six equivalent LiSb4 tetrahedra, edges with six equivalent LiSb6 octahedra, faces with two equivalent YSb6 octahedra, and faces with six equivalent LiSb4 tetrahedra. The corner-sharing octahedral tilt angles are 49°. All Li–Sb bond lengths are 3.19 Å. Y3+ is bonded to six equivalent Sb3- atoms to form YSb6 octahedra that share corners with twelve equivalent LiSb6 octahedra, corners with twelve equivalent LiSb4 tetrahedra, edges with six equivalent YSb6 octahedra, edges with six equivalent LiSb4 tetrahedra, and faces with two equivalent LiSb6 octahedra. The corner-sharing octahedral tilt angles are 49°. All Y–Sb bond lengths are 3.18 Å. Sb3- is bonded in a 10-coordinate geometry to seven Li1+ and three equivalent Y3+ atoms.
