Materials Data on SrH(IO3)2 by Materials Project

Abstract

SrH(O3I)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Sr is bonded in a 9-coordinate geometry to one H and eight O atoms. The Sr–H bond length is 2.79 Å. There are a spread of Sr–O bond distances ranging from 2.57–3.16 Å. H is bonded in a single-bond geometry to one Sr atom. There are three inequivalent O sites. In the first O site, O is bonded in a distorted bent 120 degrees geometry to one Sr and one I atom. The O–I bond length is 1.82 Å. In the second O site, O is bonded in a bent 120 degrees geometry to one Sr and one I atom. The O–I bond length is 1.84 Å. In the third O site, O is bonded in a 1-coordinate geometry to two equivalent Sr and one I atom. The O–I bond length is 1.84 Å. I is bonded in a 3-coordinate geometry to three O atoms.
