Materials Data on Rb2SnO3 by Materials Project
Rb2SnO3 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. Rb1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Rb–O bond distances ranging from 2.88–3.18 Å. Sn4+ is bonded to five O2- atoms to form distorted edge-sharing SnO5 trigonal bipyramids. There are a spread of Sn–O bond distances ranging from 1.96–2.11 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to four equivalent Rb1+ and two equivalent Sn4+ atoms. In the second O2- site, O2- is bonded in a 1-coordinate geometry to four equivalent Rb1+ and one Sn4+ atom.
