Materials Data on In(IO3)3 by Materials Project

Abstract

In(IO3)3 crystallizes in the trigonal R-3 space group. The structure is two-dimensional and consists of three In(IO3)3 sheets oriented in the (0, 0, 1) direction. In3+ is bonded in an octahedral geometry to six O2- atoms. There are three shorter (2.18 Å) and three longer (2.20 Å) In–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one In3+ 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 In3+ 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.
