Materials Data on CsIO4 by Materials Project
CsIO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cs is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Cs–O bond distances ranging from 3.16–3.40 Å. There are three inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to two equivalent Cs and one I atom. The O–I bond length is 1.80 Å. In the second O site, O is bonded in a distorted single-bond geometry to three equivalent Cs and one I atom. The O–I bond length is 1.80 Å. In the third O site, O is bonded in a distorted linear geometry to one Cs and one I atom. The O–I bond length is 1.80 Å. I is bonded in a tetrahedral geometry to four O atoms.
