The material structure described by Ir3Rh is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ir(1) is bonded to eight equivalent Ir(1) and four equivalent Rh(1) atoms to form IrIr8Rh4 cuboctahedra that share corners with twelve equivalent Ir(1)Ir8Rh4 cuboctahedra, edges with eight equivalent Rh(1)Ir12 cuboctahedra, edges with sixteen equivalent Ir(1)Ir8Rh4 cuboctahedra, faces with four equivalent Rh(1)Ir12 cuboctahedra, and faces with fourteen equivalent Ir(1)Ir8Rh4 cuboctahedra. Rh(1) is bonded to twelve equivalent Ir(1) atoms to form RhIr12 cuboctahedra that share corners with twelve equivalent Rh(1)Ir12 cuboctahedra, edges with twenty-four equivalent Ir(1)Ir8Rh4 cuboctahedra, faces with six equivalent Rh(1)Ir12 cuboctahedra, and faces with twelve equivalent Ir(1)Ir8Rh4 cuboctahedra. is represented by the CIF card [CIF]
