Materials Data on BaSn(HO)6 by Materials Project
BaSn(OH)6 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ba2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ba–O bond distances ranging from 2.73–2.91 Å. There are two inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded in an octahedral geometry to six O2- atoms. There are four shorter (2.09 Å) and two longer (2.10 Å) Sn–O bond lengths. In the second Sn4+ site, Sn4+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Sn–O bond distances ranging from 2.06–2.14 Å. There are six 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 single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Sn4+ and one H1+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+, one Sn4+, and one H1+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+, one Sn4+, and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+, one Sn4+, and one H1+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+, one Sn4+, and one H1+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+, one Sn4+, and one H1+ atom.
