Rb8SbO3 crystallizes in the cubic Pm-3m space group. Rb(1) is bonded to one Sb(1) and three equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing RbSbO3 tetrahedra. Sb(1) is bonded in a body-centered cubic geometry to eight equivalent Rb(1) atoms. O(1) is bonded in a body-centered cubic geometry to eight equivalent Rb(1) atoms.
