Materials Data on Li8HfO6 by Materials Project
Li8HfO6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four equivalent O2- atoms to form LiO4 tetrahedra that share corners with two equivalent HfO6 octahedra, corners with four equivalent LiO6 octahedra, corners with six equivalent LiO4 tetrahedra, an edgeedge with one HfO6 octahedra, edges with two equivalent LiO6 octahedra, and edges with three equivalent LiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 18–61°. There are a spread of Li–O bond distances ranging from 1.91–2.04 Å. In the second Li1+ site, Li1+ is bonded to six equivalent O2- atoms to form LiO6 octahedra that share corners with twelve equivalent LiO4 tetrahedra, edges with three equivalent LiO6 octahedra, edges with three equivalent HfO6 octahedra, and edges with six equivalent LiO4 tetrahedra. There are three shorter (2.15 Å) and three longer (2.42 Å) Li–O bond lengths. Hf4+ is bonded to six equivalent O2- atoms to form HfO6 octahedra that share corners with twelve equivalent LiO4 tetrahedra, edges with six equivalent LiO6 octahedra, and edges with six equivalent LiO4 tetrahedra. All Hf–O bond lengths are 2.12 Å. O2- is bonded in a 7-coordinate geometry to six Li1+ and one Hf4+ atom.
