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

description: Sr(H8O5)2 crystallizes in the monoclinic Cc space group. The structure is two-dimensional and consists of two Sr(H8O5)2 sheets oriented in the (0, 0, 1) direction. Sr is bonded in a 10-coordinate geometry to two H and eight O atoms. There are one shorter (2.71 Å) and one longer (2.72 Å) Sr–H bond lengths. There are a spread of Sr–O bond distances ranging from 2.55–2.86 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 0.98 Å. In the second 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 third H site, H is bonded in a linear geometry to two O atoms. There is one shorter (1.04 Å) and one longer (1.53 Å) H–O bond length. In the fourth 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 fifth H site, H is bonded in a single-bond geometry to one O atom. The H–O bond length is 0.97 Å. In the sixth H site, H is bonded in a single-bond geometry to two O atoms. There is one shorter (1.01 Å) and one longer (1.68 Å) H–O bond length. In the seventh 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 eighth H site, H is bonded in a linear geometry to two O atoms. There is one shorter (1.20 Å) and one longer (1.25 Å) H–O bond length. In the ninth 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 tenth 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 eleventh H site, H is bonded in a single-bond geometry to two O atoms. There is one shorter (1.02 Å) and one longer (1.70 Å) H–O bond length. In the twelfth 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 thirteenth H site, H is bonded in a distorted linear geometry to two O atoms. There is one shorter (1.01 Å) and one longer (1.64 Å) H–O bond length. In the fourteenth 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 fifteenth 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 sixteenth 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. There are ten inequivalent O sites. In the first O site, O is bonded in a 2-coordinate geometry to three H and one O atom. The O–O bond length is 1.49 Å. In the second O site, O is bonded in a 4-coordinate geometry to three H and one O atom. In the third O site, O is bonded in a water-like geometry to one Sr and two H atoms. In the fourth O site, O is bonded in a distorted water-like geometry to one Sr and two H atoms. In the fifth O site, O is bonded in a water-like geometry to one Sr and two H atoms. In the sixth O site, O is bonded in a distorted water-like geometry to one Sr and two H atoms. In the seventh O site, O is bonded in a water-like geometry to one Sr and two H atoms. In the eighth O site, O is bonded in a bent 120 degrees geometry to one Sr and two H atoms. In the ninth O site, O is bonded in a distorted water-like geometry to one Sr and two H atoms. In the tenth O site, O is bonded in a water-like geometry to one Sr and two H atoms.
