The structure described by Rb4CO4 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 4-coordinate geometry to four equivalent O(2) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. C(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to four equivalent Rb(2) and one C(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to two equivalent Rb(2), four equivalent Rb(1), and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
