Materials Data on SrH9ClO5 by Materials Project
(SrH9O5)2Cl2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of two hydrochloric acid molecules and one SrH9O5 sheet oriented in the (0, 1, 0) direction. In the SrH9O5 sheet, Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.59–2.75 Å. There are nine 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 0.99 Å. In the second H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.58 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.63 Å) H–O bond length. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the sixth H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.61 Å) H–O bond length. In the seventh H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.64 Å) H–O bond length. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the ninth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one Sr2+ and three H1+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to two equivalent Sr2+ and two H1+ atoms. In the third O2- site, O2- is bonded in a water-like geometry to two equivalent Sr2+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a water-like geometry to two equivalent Sr2+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Sr2+ and four H1+ atoms.
