Materials Data on Zr(IO3)4 by Materials Project

Abstract

Zr(O3I)4 crystallizes in the tetragonal P4/n space group. The structure is two-dimensional and consists of one Zr(O3I)4 sheet oriented in the (0, 0, 1) direction. Zr4+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.23 Å) and four longer (2.24 Å) Zr–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Zr4+ and one I5+ atom. The O–I bond length is 1.88 Å. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Zr4+ and one I5+ atom. The O–I bond length is 1.85 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. I5+ is bonded in a 3-coordinate geometry to three O2- atoms.
