The structure described by Ho3Sm is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to eight Ho(1,1,1) and four equivalent Sm(1) atoms to form HoSm4Ho8 cuboctahedra that share corners with four equivalent Sm(1)Ho12 cuboctahedra; corners with fourteen Ho(1,1)Sm4Ho8 cuboctahedra; edges with six equivalent Sm(1)Ho12 cuboctahedra; edges with twelve Ho(1,1,1)Sm4Ho8 cuboctahedra; faces with four equivalent Sm(1)Ho12 cuboctahedra; and faces with sixteen Ho(1,1,1)Sm4Ho8 cuboctahedra. In the second Ho site, Ho(1) is bonded to eight Ho(1,1,1) and four equivalent Sm(1) atoms to form HoSm4Ho8 cuboctahedra that share corners with four equivalent Sm(1)Ho12 cuboctahedra; corners with fourteen Ho(1,1)Sm4Ho8 cuboctahedra; edges with six equivalent Sm(1)Ho12 cuboctahedra; edges with twelve Ho(1,1,1)Sm4Ho8 cuboctahedra; faces with four equivalent Sm(1)Ho12 cuboctahedra; and faces with sixteen Ho(1,1,1)Sm4Ho8 cuboctahedra.
