Materials Data on RbH2SNO3 by Materials Project

Abstract

RbNH2SO3 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to one H1+ and seven O2- atoms. The Rb–H bond length is 3.09 Å. There are a spread of Rb–O bond distances ranging from 3.00–3.18 Å. N5+ is bonded in a distorted trigonal non-coplanar geometry to two H1+ and one S2- atom. Both N–H bond lengths are 1.03 Å. The N–S bond length is 1.68 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N5+ atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one Rb1+ and one N5+ atom. S2- is bonded in a tetrahedral geometry to one N5+ and three O2- atoms. There is two shorter (1.47 Å) and one longer (1.48 Å) S–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Rb1+ and one S2- atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Rb1+ and one S2- atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Rb1+ and one S2- atom.
