Rb2O3 is Plutonium carbide structured and crystallizes in the cubic I-43d space group. Rb(1) is bonded in a 6-coordinate geometry to nine equivalent O(1) atoms. O(1) is bonded to six equivalent Rb(1) and one O(1) atom to form a mixture of distorted corner, face, and edge-sharing ORb6O pentagonal bipyramids.
