Materials Data on Sr2Sn(HO)8 by Materials Project
Sr2Sn(OH)8 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one Sr2Sn(OH)8 sheet oriented in the (0, 0, 1) direction. Sr2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Sr–O bond distances ranging from 2.51–2.81 Å. Sn4+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Sn–O bond distances ranging from 2.08–2.13 Å. There are four 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 0.98 Å. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- atom. The H–O bond length is 1.03 Å. In the third 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 fourth 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 four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Sr2+, one Sn4+, and one H1+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Sr2+, one Sn4+, and one H1+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Sr2+, one Sn4+, and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Sr2+ and one H1+ atom.
