The crystal structure described by Rb4CO4 is alpha Po structured and crystallizes in the trigonal R3 space group. The structure is zero-dimensional and consists of three Rb4CO4 clusters. There are two 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 3-coordinate geometry to one O(2) and two 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 single-bond geometry to one Rb(1), two equivalent Rb(2), and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Rb(2) and one C(1) atom. is represented by the CIF card [CIF]
