Materials Data on LiIO3 by Materials Project

Abstract

LiIO3 crystallizes in the hexagonal P6_322 space group. The structure is three-dimensional. Li1+ is bonded to six equivalent O2- atoms to form LiO6 octahedra that share corners with six equivalent IO6 octahedra, edges with three equivalent IO6 octahedra, and faces with two equivalent LiO6 octahedra. The corner-sharing octahedral tilt angles are 48°. All Li–O bond lengths are 2.10 Å. O2- is bonded in a 4-coordinate geometry to two equivalent Li1+ and two equivalent I5+ atoms. Both O–I bond lengths are 2.13 Å. I5+ is bonded to six equivalent O2- atoms to form IO6 octahedra that share corners with six equivalent LiO6 octahedra, corners with six equivalent IO6 octahedra, and edges with three equivalent LiO6 octahedra. The corner-sharing octahedra tilt angles range from 48–50°.
