The crystal structure described by Rb(IrO2)6 crystallizes in the tetragonal I4/m space group. Rb(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(3) and four equivalent O(4) atoms. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form a mixture of corner and edge-sharing IrO6 octahedra. The corner-sharing octahedral tilt angles are 53°. In the second Ir site, Ir(2) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form a mixture of corner and edge-sharing IrO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are four inequivalent O sites. In the first O site, O(3) is bonded to one Rb(1), one Ir(2), and two equivalent Ir(1) atoms to form a mixture of distorted corner and edge-sharing ORbIr3 trigonal pyramids. In the second O site, O(4) is bonded in a 3-coordinate geometry to two equivalent Rb(1), one Ir(2), and two equivalent Ir(1) atoms. In the third O site, O(1) is bonded in a trigonal planar geometry to one Ir(2) and two equivalent Ir(1) atoms. In the fourth O site, O(2) is bonded in a trigonal planar geometry to one Ir(2) and two equivalent Ir(1) atoms. is represented by the CIF card [CIF]
