IrCo3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ir(1) is bonded to twelve equivalent Co(1) atoms to form IrCo12 cuboctahedra that share corners with twelve equivalent Ir(1)Co12 cuboctahedra, edges with twenty-four equivalent Co(1)Co8Ir4 cuboctahedra, faces with six equivalent Ir(1)Co12 cuboctahedra, and faces with twelve equivalent Co(1)Co8Ir4 cuboctahedra. Co(1) is bonded to four equivalent Ir(1) and eight equivalent Co(1) atoms to form CoCo8Ir4 cuboctahedra that share corners with twelve equivalent Co(1)Co8Ir4 cuboctahedra, edges with eight equivalent Ir(1)Co12 cuboctahedra, edges with sixteen equivalent Co(1)Co8Ir4 cuboctahedra, faces with four equivalent Ir(1)Co12 cuboctahedra, and faces with fourteen equivalent Co(1)Co8Ir4 cuboctahedra.
