The material structure described by Rb4CO4 crystallizes in the trigonal R3m space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a distorted trigonal planar geometry to one O(2) and two equivalent O(1) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. C(1) is bonded in a tetrahedral geometry to one O(2) and three equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Rb(1), two equivalent Rb(2), and one C(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to three equivalent Rb(1) and one C(1) atom. is represented by the CIF card [CIF]
