Materials Data on Cs2Zr(IO3)6 by Materials Project
Cs2Zr(O3I)6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Cs1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are six shorter (3.22 Å) and three longer (3.27 Å) Cs–O bond lengths. Zr4+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Zr–O bond lengths are 2.11 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Cs1+ and one I5+ atom. The O–I bond length is 1.83 Å. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cs1+, one Zr4+, and one I5+ atom. The O–I bond length is 1.88 Å. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Cs1+ and one I5+ atom. The O–I bond length is 1.82 Å. I5+ is bonded in a 5-coordinate geometry to three O2- atoms.
