Rb9O2 is Indium-like structured and crystallizes in the monoclinic P2_1/m space group. The structure is zero-dimensional and consists of two Rb9O2 clusters. There are six inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a single-bond geometry to one O(1) atom. In the second Rb site, Rb(2) is bonded in an L-shaped geometry to one O(1) and one O(2) atom. In the third Rb site, Rb(3) is bonded in a single-bond geometry to one O(2) atom. In the fourth Rb site, Rb(4) is bonded in a single-bond geometry to one O(1) atom. In the fifth Rb site, Rb(5) is bonded in an L-shaped geometry to one O(1) and one O(2) atom. In the sixth Rb site, Rb(6) is bonded in a single-bond geometry to one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Rb(4), one Rb(5), two equivalent Rb(1), and two equivalent Rb(2) atoms to form face-sharing ORb6 octahedra. In the second O site, O(2) is bonded to one Rb(3), one Rb(5), two equivalent Rb(2), and two equivalent Rb(6) atoms to form face-sharing ORb6 octahedra.
