Rb3SbO3 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 3-coordinate geometry to three 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 6-coordinate geometry to six equivalent O(1) atoms. Sb(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent O(1) atoms. O(1) is bonded in a 6-coordinate geometry to one Rb(1), two equivalent Rb(2), two equivalent Rb(3), and one Sb(1) atom.
Rb3SbO3 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 3-coordinate geometry to three equivalent O(1) atoms. All Rb(1)-O(1) bond lengths are 2.77 Å. 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 (3.03 Å) Rb(2)-O(1) bond lengths. In the third Rb site, Rb(3) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. There are three shorter (2.88 Å) and three longer (3.08 Å) Rb(3)-O(1) bond lengths. Sb(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent O(1) atoms. All Sb(1)-O(1) bond lengths are 1.95 Å. O(1) is bonded in a 6-coordinate geometry to one Rb(1), two equivalent Rb(2), two equivalent Rb(3), and one Sb(1) atom.
