Materials Data on Rb4SnO3 by Materials Project

Abstract

Rb4SnO3 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. there are four inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a distorted trigonal planar geometry to three O2- atoms. There are a spread of Rb–O bond distances ranging from 2.87–3.12 Å. In the second Rb1+ site, Rb1+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Rb–O bond distances ranging from 2.81–2.92 Å. In the third Rb1+ site, Rb1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Rb–O bond distances ranging from 2.83–2.96 Å. In the fourth Rb1+ site, Rb1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Rb–O bond distances ranging from 2.85–3.22 Å. Sn2+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are two shorter (2.09 Å) and one longer (2.10 Å) Sn–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to five Rb1+ and one Sn2+ atom. In the second O2- site, O2- is bonded in a 6-coordinate geometry to five Rb1+ and one Sn2+ atom. In the third O2- site, O2- is bonded in a 6-coordinate geometry to five Rb1+ and one Sn2+ atom.
