Materials Data on ErH3(SO4)3 by Materials Project

Abstract

ErH3(SO4)3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Er3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Er–O bond distances ranging from 2.27–2.63 Å. There are three 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 1.01 Å. In the second 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 third 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 three inequivalent S6+ sites. In the first S6+ site, S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.45–1.57 Å. In the second S6+ site, S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.45–1.60 Å. In the third S6+ site, S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.46–1.57 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Er3+ and one S6+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Er3+ and one S6+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one S6+ atom. In the fourth O2- site, O2- is bonded in a water-like geometry to one H1+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one H1+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Er3+ and one S6+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Er3+ and one S6+ atom. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one H1+ and one S6+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Er3+ and one S6+ atom. In the tenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Er3+ and one S6+ atom. In the eleventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Er3+ and one S6+ atom. In the twelfth O2- site, O2- is bonded in a distorted linear geometry to one Er3+ and one S6+ atom.
