Materials Data on LiO3 by Materials Project
LiO3 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. Li is bonded in a 6-coordinate geometry to six equivalent O atoms. There are four shorter (2.23 Å) and two longer (2.25 Å) Li–O bond lengths. There are two inequivalent O sites. In the first O site, O is bonded in a distorted water-like geometry to two equivalent O atoms. Both O–O bond lengths are 1.36 Å. In the second O site, O is bonded to three equivalent Li and one O atom to form a mixture of distorted edge and corner-sharing OLi3O tetrahedra.
