Materials Data on RbH3(SeO3)2 by Materials Project

Abstract

RbH3(SeO3)2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.96–3.33 Å. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.57 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.06 Å) and one longer (1.48 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.04 Å) and one longer (1.55 Å) H–O bond length. There are two inequivalent Se4+ sites. In the first Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.68 Å) and two longer (1.79 Å) Se–O bond length. In the second Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.70–1.80 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Rb1+, one H1+, and one Se4+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Rb1+, one H1+, and one Se4+ atom. In the third O2- site, O2- is bonded in a distorted water-like geometry to two equivalent Rb1+, one H1+, and one Se4+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one Rb1+, one H1+, and one Se4+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Rb1+, one H1+, and one Se4+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Rb1+, one H1+, and one Se4+ atom.
