WIr crystallizes in the hexagonal P-6m2 space group. W(1) is bonded to six equivalent W(1) and six equivalent Ir(1) atoms to form WIr6W6 cuboctahedra that share corners with eighteen equivalent W(1)Ir6W6 cuboctahedra, edges with six equivalent W(1)Ir6W6 cuboctahedra, edges with twelve equivalent Ir(1)Ir6W6 cuboctahedra, faces with eight equivalent W(1)Ir6W6 cuboctahedra, and faces with twelve equivalent Ir(1)Ir6W6 cuboctahedra. Ir(1) is bonded to six equivalent W(1) and six equivalent Ir(1) atoms to form IrIr6W6 cuboctahedra that share corners with eighteen equivalent Ir(1)Ir6W6 cuboctahedra, edges with six equivalent Ir(1)Ir6W6 cuboctahedra, edges with twelve equivalent W(1)Ir6W6 cuboctahedra, faces with eight equivalent Ir(1)Ir6W6 cuboctahedra, and faces with twelve equivalent W(1)Ir6W6 cuboctahedra.
