Materials Data on LiIO3 by Materials Project

Abstract

LiIO3 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. Li1+ is bonded to five O2- atoms to form distorted edge-sharing LiO5 trigonal bipyramids. There are a spread of Li–O bond distances ranging from 1.99–2.16 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted T-shaped geometry to two equivalent Li1+ and one I5+ atom. The O–I bond length is 1.82 Å. In the second O2- site, O2- is bonded in a bent 120 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 3-coordinate 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.
