Materials Data on Rb3SbO3 by Materials Project

Abstract

Rb3SbO3 crystallizes in the cubic P2_13 space group. The structure is three-dimensional. there are three inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a distorted T-shaped geometry to three equivalent O2- atoms. All Rb–O bond lengths are 2.85 Å. In the second Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. There are three shorter (2.93 Å) and three longer (3.10 Å) Rb–O bond lengths. In the third Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. There are three shorter (2.92 Å) and three longer (3.14 Å) Rb–O bond lengths. Sb3+ is bonded in a trigonal non-coplanar geometry to three equivalent O2- atoms. All Sb–O bond lengths are 1.97 Å. O2- is bonded in a 6-coordinate geometry to five Rb1+ and one Sb3+ atom.
