The structure described by Rb5(CoO2)2 crystallizes in the triclinic P-1 space group. There are five inequivalent Rb sites. In the first Rb site, Rb(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form a mixture of distorted corner and edge-sharing RbO4 tetrahedra. In the second Rb site, Rb(2) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form a mixture of distorted corner and edge-sharing RbO4 tetrahedra. In the third Rb site, Rb(3) is bonded in a 4-coordinate geometry to one O(3), one O(4), and two equivalent O(1) atoms. In the fourth Rb site, Rb(4) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(2), and one O(4) atom. In the fifth Rb site, Rb(5) is bonded in a 3-coordinate geometry to one O(3) and two equivalent O(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted T-shaped geometry to one O(1) and two equivalent O(3) atoms. In the second Co site, Co(2) is bonded in a linear geometry to one O(2) and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to one Rb(1), one Rb(2), one Rb(4), two equivalent Rb(3), and one Co(1) atom. In the second O site, O(2) is bonded in a 6-coordinate geometry to one Rb(1), one Rb(2), one Rb(4), two equivalent Rb(5), and one Co(2) atom. In the third O site, O(3) is bonded to one Rb(1), one Rb(2), one Rb(3), one Rb(5), and two equivalent Co(1) atoms to form distorted edge-sharing ORb4Co2 octahedra. In the fourth O site, O(4) is bonded in a 1-coordinate geometry to one Rb(1), one Rb(2), one Rb(3), one Rb(4), and one Co(2) atom. is represented by the CIF card [CIF]
