The structure described by RbCO2 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 8-coordinate geometry to one O(4), two equivalent O(2), two equivalent O(3), and three equivalent O(1) atoms. In the second Rb site, Rb(2) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(4) atom. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Rb(2), three equivalent Rb(1), and one C(2) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Rb(1), two equivalent Rb(2), and one C(2) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Rb(1), two equivalent Rb(2), and one C(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Rb(1), two equivalent Rb(2), and one C(1) atom. is represented by the CIF card [CIF]
