Materials Data on LiIO3 by Materials Project

Abstract

LiIO3 crystallizes in the tetragonal P4_2/n space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form distorted corner-sharing LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.97–2.02 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one Li1+ and one I5+ atom. The O–I bond length is 1.83 Å. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Li1+ and one I5+ atom. The O–I bond length is 1.83 Å. In the third O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Li1+ and one I5+ atom. The O–I bond length is 1.83 Å. I5+ is bonded in a 3-coordinate geometry to three O2- atoms.
