CoMo crystallizes in the hexagonal P-6m2 space group. Mo(1) is bonded to six equivalent Mo(1) and six equivalent Co(1) atoms to form distorted MoCo6Mo6 cuboctahedra that share corners with eighteen equivalent Mo(1)Co6Mo6 cuboctahedra, edges with six equivalent Mo(1)Co6Mo6 cuboctahedra, edges with twelve equivalent Co(1)Co6Mo6 cuboctahedra, faces with eight equivalent Mo(1)Co6Mo6 cuboctahedra, and faces with twelve equivalent Co(1)Co6Mo6 cuboctahedra. Co(1) is bonded to six equivalent Mo(1) and six equivalent Co(1) atoms to form distorted CoCo6Mo6 cuboctahedra that share corners with eighteen equivalent Co(1)Co6Mo6 cuboctahedra, edges with six equivalent Co(1)Co6Mo6 cuboctahedra, edges with twelve equivalent Mo(1)Co6Mo6 cuboctahedra, faces with eight equivalent Co(1)Co6Mo6 cuboctahedra, and faces with twelve equivalent Mo(1)Co6Mo6 cuboctahedra.
