The structure described by YSc crystallizes in the hexagonal P-6m2 space group. Y(1) is bonded to six equivalent Y(1) and six equivalent Sc(1) atoms to form YY6Sc6 cuboctahedra that share corners with eighteen equivalent Y(1)Y6Sc6 cuboctahedra, edges with six equivalent Y(1)Y6Sc6 cuboctahedra, edges with twelve equivalent Sc(1)Y6Sc6 cuboctahedra, faces with eight equivalent Y(1)Y6Sc6 cuboctahedra, and faces with twelve equivalent Sc(1)Y6Sc6 cuboctahedra. Sc(1) is bonded to six equivalent Y(1) and six equivalent Sc(1) atoms to form ScY6Sc6 cuboctahedra that share corners with eighteen equivalent Sc(1)Y6Sc6 cuboctahedra, edges with six equivalent Sc(1)Y6Sc6 cuboctahedra, edges with twelve equivalent Y(1)Y6Sc6 cuboctahedra, faces with eight equivalent Sc(1)Y6Sc6 cuboctahedra, and faces with twelve equivalent Y(1)Y6Sc6 cuboctahedra. is represented by the CIF file [CIF]
