Rb3BiO3 is Calaverite-derived structured and crystallizes in the cubic P2_13 space group. There are three inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. In the third Rb site, Rb(3) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. Bi(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. O(1) is bonded in a 6-coordinate geometry to one Rb(3), two equivalent Rb(1), two equivalent Rb(2), and one Bi(1) atom.

In the first Rb site, Rb(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. There are three shorter (2.89 Å) and three longer (3.08 Å) Rb(1)-O(1) bond lengths. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. There are three shorter (2.91 Å) and three longer (3.04 Å) Rb(2)-O(1) bond lengths. In the third Rb site, Rb(3) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. All Rb(3)-O(1) bond lengths are 2.75 Å. Bi(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. All Bi(1)-O(1) bond lengths are 2.08 Å. O(1) is bonded in a 6-coordinate geometry to one Rb(3), two equivalent Rb(1), two equivalent Rb(2), and one Bi(1) atom.
