Materials Data on S(IO3)2 by Materials Project

Abstract

S(O3I)2 crystallizes in the monoclinic C2/c space group. The structure is two-dimensional and consists of two S(O3I)2 sheets oriented in the (0, 0, 1) direction. S2+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.49 Å) and two longer (1.51 Å) S–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one S2+ and one I5+ atom. The O–I bond length is 2.46 Å. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one S2+ and one I5+ atom. The O–I bond length is 2.38 Å. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent I5+ atoms. There are one shorter (2.00 Å) and one longer (2.01 Å) O–I bond lengths. I5+ is bonded in a square co-planar geometry to four O2- atoms.
