Materials Data on Sr(HO)2 by Materials Project

Abstract

Sr(OH)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sr2+ is bonded in a 7-coordinate geometry to one H1+ and six O2- atoms. The Sr–H bond length is 2.54 Å. There are a spread of Sr–O bond distances ranging from 2.54–2.66 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one Sr2+ and one O2- atom. The H–O bond length is 0.98 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to three equivalent Sr2+ and one H1+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to three equivalent Sr2+ and one H1+ atom.
