The compound described by Rb6CdO4 crystallizes in the hexagonal P6_3mc space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 5-coordinate geometry to one O(1) and four equivalent O(2) atoms. In the second Rb site, Rb(2) is bonded in a 4-coordinate geometry to one O(1) and three equivalent O(2) atoms. Cd(1) is bonded in a tetrahedral geometry to one O(1) and three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 7-coordinate geometry to three equivalent Rb(1), three equivalent Rb(2), and one Cd(1) atom. In the second O site, O(2) is bonded in a 8-coordinate geometry to three equivalent Rb(2), four equivalent Rb(1), and one Cd(1) atom. is represented by the CIF card [CIF]
