Materials Data on Rb6CdO4 by Materials Project

Abstract

Rb6CdO4 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Rb–O bond distances ranging from 2.89–3.28 Å. In the second Rb1+ site, Rb1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Rb–O bond distances ranging from 2.81–3.07 Å. Cd2+ is bonded in a tetrahedral geometry to four O2- atoms. There are one shorter (2.24 Å) and three longer (2.33 Å) Cd–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to six Rb1+ and one Cd2+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to seven Rb1+ and one Cd2+ atom.
