Materials Data on Rb3BiO3 by Materials Project
Rb3BiO3 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 6-coordinate geometry to six equivalent O2- atoms. There are three shorter (2.94 Å) and three longer (3.17 Å) Rb–O bond lengths. In the second Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. There are three shorter (2.95 Å) and three longer (3.13 Å) Rb–O bond lengths. In the third Rb1+ site, Rb1+ is bonded in a distorted T-shaped geometry to three equivalent O2- atoms. All Rb–O bond lengths are 2.78 Å. Bi3+ is bonded in a distorted trigonal non-coplanar geometry to three equivalent O2- atoms. All Bi–O bond lengths are 2.10 Å. O2- is bonded in a 6-coordinate geometry to five Rb1+ and one Bi3+ atom.
