IrO2 is Hydrophilite structured and crystallizes in the tetragonal P4_2/mnm space group. Ir(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing IrO6 octahedra. The corner-sharing octahedral tilt angles are 52°. O(1) is bonded in a trigonal planar geometry to three equivalent Ir(1) atoms.

The corner-sharing octahedral tilt angles are 52°. There are two shorter (1.97 Å) and four longer (2.00 Å) Ir(1)-O(1) bond lengths. O(1) is bonded in a trigonal planar geometry to three equivalent Ir(1) atoms.
