The material described by Rb2O3 crystallizes in the tetragonal I-42d space group. Rb(1) is bonded in a 7-coordinate geometry to three equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to six equivalent Rb(1) and one O(1) atom to form a mixture of distorted face, corner, and edge-sharing ORb6O pentagonal bipyramids. In the second O site, O(2) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one O(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
