Materials Data on Rb4SnO3 by Materials Project
Rb4SnO3 crystallizes in the monoclinic Cc 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 non-coplanar geometry to three O2- atoms. There are a spread of Rb–O bond distances ranging from 2.76–2.96 Å. In the second Rb1+ site, Rb1+ is bonded to five O2- atoms to form a mixture of distorted corner and edge-sharing RbO5 trigonal bipyramids. There are a spread of Rb–O bond distances ranging from 2.82–3.29 Å. In the third Rb1+ site, Rb1+ is bonded to five O2- atoms to form a mixture of distorted corner and edge-sharing RbO5 square pyramids. There are a spread of Rb–O bond distances ranging from 2.88–3.04 Å. In the fourth Rb1+ site, Rb1+ is bonded in a bent 150 degrees geometry to two equivalent O2- atoms. There are one shorter (2.77 Å) and one longer (2.80 Å) Rb–O bond lengths. Sn2+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Sn–O bond distances ranging from 2.07–2.09 Å. 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.
