Materials Data on Rb2O by Materials Project

Abstract

Rb2O is trigonal omega structured and crystallizes in the triclinic P1 space group. The structure is two-dimensional and consists of one Rb2O sheet oriented in the (1, 0, 0) direction. there are six 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 2.78–2.82 Å. In the second 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 2.78–2.82 Å. In the third 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 2.78–2.82 Å. In the fourth 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 2.78–2.81 Å. In the fifth 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 2.78–2.82 Å. In the sixth 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 2.78–2.81 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to six Rb1+ atoms to form edge-sharing ORb6 octahedra. In the second O2- site, O2- is bonded to six Rb1+ atoms to form edge-sharing ORb6 octahedra. In the third O2- site, O2- is bonded to six Rb1+ atoms to form edge-sharing ORb6 octahedra.
