title: Materials Data on Sr(H8O5)2 by Materials Project

description: Sr(H8O5)2 crystallizes in the triclinic P1 space group. The structure is two-dimensional and consists of two Sr(H8O5)2 sheets oriented in the (0, 0, 1) direction. In one of the Sr(H8O5)2 sheets, Sr is bonded in a body-centered cubic geometry to eight O atoms. There are a spread of Sr–O bond distances ranging from 2.61–2.72 Å. There are sixteen 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 1.00 Å. In the second H site, H is bonded in a single-bond geometry to two O atoms. There is one shorter (1.00 Å) and one longer (1.74 Å) H–O bond length. In the third 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 fourth H site, H is bonded in a linear geometry to two O atoms. There is one shorter (1.05 Å) and one longer (1.50 Å) H–O bond length. In the fifth H site, H is bonded in a distorted single-bond geometry to two O atoms.
