Materials Data on RbSnI3 by Materials Project
RbSnI3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rb1+ is bonded in a 9-coordinate geometry to nine I1- atoms. There are a spread of Rb–I bond distances ranging from 3.89–4.26 Å. Sn2+ is bonded to six I1- atoms to form edge-sharing SnI6 octahedra. There are a spread of Sn–I bond distances ranging from 3.04–3.42 Å. There are three inequivalent I1- sites. In the first I1- site, I1- is bonded in a 5-coordinate geometry to four equivalent Rb1+ and one Sn2+ atom. In the second I1- site, I1- is bonded in a 5-coordinate geometry to two equivalent Rb1+ and three equivalent Sn2+ atoms. In the third I1- site, I1- is bonded in a 5-coordinate geometry to three equivalent Rb1+ and two equivalent Sn2+ atoms.
