Materials Data on Li6TeO6 by Materials Project

Abstract

Li6(TeO6) crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Li1+ is bonded to five equivalent O2- atoms to form distorted LiO5 square pyramids that share a cornercorner with one TeO6 octahedra, corners with eight equivalent LiO5 square pyramids, edges with two equivalent TeO6 octahedra, and edges with six equivalent LiO5 square pyramids. The corner-sharing octahedral tilt angles are 13°. There are a spread of Li–O bond distances ranging from 1.98–2.41 Å. Te6+ is bonded to six equivalent O2- atoms to form TeO6 octahedra that share corners with six equivalent LiO5 square pyramids and edges with twelve equivalent LiO5 square pyramids. All Te–O bond lengths are 1.96 Å. O2- is bonded to five equivalent Li1+ and one Te6+ atom to form a mixture of distorted corner and edge-sharing OLi5Te octahedra. The corner-sharing octahedra tilt angles range from 0–19°.
