The compound described by RbO2I crystallizes in the tetragonal I4_1/a space group. The structure consists of a RbO2I framework. Rb(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded in a 3-coordinate geometry to one Rb(1), one O(1), and one I(1) atom. I(1) is bonded in a linear geometry to two equivalent O(1) atoms. is represented by the CIF card [CIF]
