Materials Data on Rb2SnO2 by Materials Project
Rb2SnO2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 4-coordinate geometry to three O2- atoms. There are a spread of Rb–O bond distances ranging from 2.82–2.89 Å. In the second Rb1+ site, Rb1+ is bonded in a see-saw-like geometry to four O2- atoms. There are a spread of Rb–O bond distances ranging from 2.90–2.99 Å. Sn2+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are one shorter (2.03 Å) and two longer (2.12 Å) Sn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two Rb1+ and two equivalent Sn2+ atoms. In the second O2- site, O2- is bonded to five Rb1+ and one Sn2+ atom to form a mixture of distorted edge and corner-sharing ORb5Sn octahedra. The corner-sharing octahedra tilt angles range from 7–11°.
