The structure described by IrSb3 is Skutterudite structured and crystallizes in the cubic Im-3 space group. Ir(1) is bonded to six equivalent Sb(1) atoms to form corner-sharing IrSb6 octahedra. The corner-sharing octahedral tilt angles are 56°. Sb(1) is bonded in a 4-coordinate geometry to two equivalent Ir(1) and two equivalent Sb(1) atoms. is represented by the CIF card [CIF]
