MoRh crystallizes in the hexagonal P-6m2 space group. Mo(1) is bonded to six equivalent Mo(1) and six equivalent Rh(1) atoms to form MoMo6Rh6 cuboctahedra that share corners with eighteen equivalent Mo(1)Mo6Rh6 cuboctahedra, edges with six equivalent Mo(1)Mo6Rh6 cuboctahedra, edges with twelve equivalent Rh(1)Mo6Rh6 cuboctahedra, faces with eight equivalent Mo(1)Mo6Rh6 cuboctahedra, and faces with twelve equivalent Rh(1)Mo6Rh6 cuboctahedra. Rh(1) is bonded to six equivalent Mo(1) and six equivalent Rh(1) atoms to form RhMo6Rh6 cuboctahedra that share corners with eighteen equivalent Rh(1)Mo6Rh6 cuboctahedra, edges with six equivalent Rh(1)Mo6Rh6 cuboctahedra, edges with twelve equivalent Mo(1)Mo6Rh6 cuboctahedra, faces with eight equivalent Rh(1)Mo6Rh6 cuboctahedra, and faces with twelve equivalent Mo(1)Mo6Rh6 cuboctahedra.
