Materials Data on Rb3SbO3 by Materials Project

Abstract

Rb3SbO3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three 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 2.78–3.23 Å. In the second 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 2.80–3.32 Å. In the third 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 2.76–3.05 Å. Sb3+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.98 Å) and one longer (1.99 Å) Sb–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to four Rb1+ and one Sb3+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to four Rb1+ and one Sb3+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to five Rb1+ and one Sb3+ atom.
