Materials Data on Sr(H2O3)2 by Materials Project

Abstract

Sr(H2O3)2 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. Sr is bonded in a 1-coordinate geometry to one H and nine O atoms. The Sr–H bond length is 2.66 Å. There are a spread of Sr–O bond distances ranging from 2.61–3.06 Å. There are four inequivalent H sites. In the first H site, H is bonded in a single-bond geometry to one O atom. The H–O bond length is 0.98 Å. In the second H site, H is bonded in a single-bond geometry to one Sr and one O atom. The H–O bond length is 0.98 Å. In the third H site, H is bonded in a single-bond geometry to one O atom. The H–O bond length is 0.99 Å. In the fourth H site, H is bonded in a linear geometry to two O atoms. There is one shorter (1.03 Å) and one longer (1.55 Å) H–O bond length. There are six inequivalent O sites. In the first O site, O is bonded in a water-like geometry to one Sr and two H atoms. In the second O site, O is bonded in a single-bond geometry to two equivalent Sr, one H, and one O atom. The O–O bond length is 1.48 Å. In the third O site, O is bonded in a single-bond geometry to two equivalent Sr and one H atom. In the fourth O site, O is bonded in a distorted trigonal non-coplanar geometry to two equivalent Sr and one O atom. In the fifth O site, O is bonded in a distorted single-bond geometry to one Sr, one H, and one O atom. The O–O bond length is 1.32 Å. In the sixth O site, O is bonded in a 1-coordinate geometry to one Sr and one O atom.
