The compound described by RbO3I crystallizes in the trigonal R3m space group. Rb(1) is bonded to twelve equivalent O(1) atoms to form a mixture of distorted face and corner-sharing RbO12 cuboctahedra. O(1) is bonded in a distorted single-bond geometry to four equivalent Rb(1) and one I(1) atom. I(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
