Materials Data on RbLi2(IO3)3 by Materials Project
RbLi2(O3I)3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Rb1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 2.94–3.22 Å. There are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form corner-sharing LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.95–2.05 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form corner-sharing LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.95–2.01 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Li1+, and one I5+ atom. The O–I bond length is 1.84 Å. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+, 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 distorted single-bond geometry to one I5+ atom. The O–I bond length is 1.83 Å. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Li1+, and one I5+ atom. The O–I bond length is 1.82 Å.
