The material described by CsO2 crystallizes in the orthorhombic Cmmm space group. Cs(1) is bonded to twelve equivalent O(1) atoms to form a mixture of edge and face-sharing CsO12 cuboctahedra. O(1) is bonded in a 7-coordinate geometry to six equivalent Cs(1) and one O(1) atom. is represented by the CIF card [CIF]
