Title: Materials Data on Sr(IO3)2 by Materials Project

Abstract

Sr(IO3)2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is two-dimensional and consists of two Sr(IO3)2 sheets oriented in the (0, 0, 1) direction. Sr2+ is bonded to seven O2- atoms to form distorted corner-sharing SrO7 pentagonal bipyramids. There are a spread of Sr–O bond distances ranging from 2.50–2.67 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Sr2+ and one I5+ atom. The O–I bond length is 1.85 Å. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sr2+ and one I5+ atom. The O–I bond length is 1.84 Å. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Sr2+ and one I5+ atom. The O–I bond length is 1.84 Å. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Sr2+ and one I5+ atom. The O–I bond length is 1.85 Å. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Sr2+ and two I5+ atoms. There are one shorter (1.86 Å) and one longer (2.67 Å) O–I bond lengths.more » In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sr2+ and one I5+ atom. The O–I bond length is 1.84 Å. There are two inequivalent I5+ sites. In the first I5+ site, I5+ is bonded in a 3-coordinate geometry to four O2- atoms. In the second I5+ site, I5+ is bonded in a 3-coordinate geometry to three O2- atoms.« less
