Rb2O2 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 7-coordinate geometry to seven equivalent O(1) atoms. O(1) is bonded to seven equivalent Rb(1) atoms to form a mixture of distorted edge, corner, and face-sharing ORb7 pentagonal bipyramids.
Rb2O2 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 7-coordinate geometry to seven equivalent O(1) atoms. There are six shorter (2.94 Å) and one longer (3.08 Å) Rb(1)-O(1) bond length. O(1) is bonded to seven equivalent Rb(1) atoms to form a mixture of distorted edge, corner, and face-sharing ORb7 pentagonal bipyramids.
