The structure described by RbO2 crystallizes in the tetragonal P4/mmm space group. Rb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form a mixture of edge and corner-sharing RbO6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent Rb(1) atoms. In the second O site, O(2) is bonded in a square co-planar geometry to four equivalent Rb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
