Materials Data on Tl(IO3)3 by Materials Project

Abstract

Tl(IO3)3 crystallizes in the trigonal R-3 space group. The structure is two-dimensional and consists of three Tl(IO3)3 sheets oriented in the (0, 0, 1) direction. Tl3+ is bonded in an octahedral geometry to six O2- atoms. There are three shorter (2.28 Å) and three longer (2.29 Å) Tl–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 Tl3+ and one I5+ atom. The O–I bond length is 1.84 Å. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one I5+ atom. The O–I bond length is 1.84 Å. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Tl3+ and one I5+ atom. The O–I bond length is 1.86 Å. I5+ is bonded in a 4-coordinate geometry to three O2- atoms.
