The material described by IrCo crystallizes in the hexagonal P-6m2 space group. Ir(1) is bonded to six equivalent Ir(1) and six equivalent Co(1) atoms to form distorted IrCo6Ir6 cuboctahedra that share corners with eighteen equivalent Ir(1)Co6Ir6 cuboctahedra, edges with six equivalent Ir(1)Co6Ir6 cuboctahedra, edges with twelve equivalent Co(1)Co6Ir6 cuboctahedra, faces with eight equivalent Ir(1)Co6Ir6 cuboctahedra, and faces with twelve equivalent Co(1)Co6Ir6 cuboctahedra.
