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 10-coordinate geometry to ten O atoms. There are a spread of Sr–O bond distances ranging from 2.59–2.81 Å. There are four inequivalent H sites. In the first H site, H is bonded in a linear geometry to two O atoms. There is one shorter (1.04 Å) and one longer (1.52 Å) H–O bond length. In the second H site, H is bonded in a linear geometry to two O atoms. There is one shorter (1.06 Å) and one longer (1.47 Å) H–O bond length. In the third H site, H is bonded in a linear geometry to two O atoms. There is one shorter (1.10 Å) and one longer (1.38 Å) H–O bond length. In the fourth H site, H is bonded in a linear geometry to two O atoms. There is one shorter (1.14 Å) and one longer (1.31 Å) H–O bond length. There are six inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to two equivalent Sr and one H atom. In the second O site, O is bonded in a single-bond geometry to two equivalent Sr and one H atom. 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 single-bond geometry to two equivalent Sr and one H atom. In the fifth O site, O is bonded in a distorted bent 120 degrees geometry to one Sr and two H atoms. In the sixth O site, O is bonded in a 2-coordinate geometry to one Sr and two H atoms.
