The structure described by Cs2O2 is alpha boron-derived structured and crystallizes in the orthorhombic Immm space group. Cs(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. O(1) is bonded to six equivalent Cs(1) and one O(1) atom to form a mixture of distorted edge, face, and corner-sharing OCs6O pentagonal bipyramids. is represented by the CIF file [CIF]
