The compound described by RbO3 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a 9-coordinate geometry to one O(2), four equivalent O(1), and four equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to one Rb(1), one O(1), and one O(3) atom. In the second O site, O(1) is bonded to four equivalent Rb(1) and one O(2) atom to form a mixture of distorted corner, face, and edge-sharing ORb4O trigonal bipyramids. In the third O site, O(3) is bonded to four equivalent Rb(1) and one O(2) atom to form a mixture of distorted corner, face, and edge-sharing ORb4O trigonal bipyramids. is represented by the CIF file [CIF]
