IrRh3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ir(1) is bonded to twelve equivalent Rh(1) atoms to form IrRh12 cuboctahedra that share corners with twelve equivalent Ir(1)Rh12 cuboctahedra, edges with twenty-four equivalent Rh(1)Ir4Rh8 cuboctahedra, faces with six equivalent Ir(1)Rh12 cuboctahedra, and faces with twelve equivalent Rh(1)Ir4Rh8 cuboctahedra. Rh(1) is bonded to four equivalent Ir(1) and eight equivalent Rh(1) atoms to form RhIr4Rh8 cuboctahedra that share corners with twelve equivalent Rh(1)Ir4Rh8 cuboctahedra, edges with eight equivalent Ir(1)Rh12 cuboctahedra, edges with sixteen equivalent Rh(1)Ir4Rh8 cuboctahedra, faces with four equivalent Ir(1)Rh12 cuboctahedra, and faces with fourteen equivalent Rh(1)Ir4Rh8 cuboctahedra.
