HoSm3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ho(1) is bonded to twelve equivalent Sm(1) atoms to form HoSm12 cuboctahedra that share corners with twelve equivalent Ho(1)Sm12 cuboctahedra, edges with twenty-four equivalent Sm(1)Sm8Ho4 cuboctahedra, faces with six equivalent Ho(1)Sm12 cuboctahedra, and faces with twelve equivalent Sm(1)Sm8Ho4 cuboctahedra. Sm(1) is bonded to four equivalent Ho(1) and eight equivalent Sm(1) atoms to form SmSm8Ho4 cuboctahedra that share corners with twelve equivalent Sm(1)Sm8Ho4 cuboctahedra, edges with eight equivalent Ho(1)Sm12 cuboctahedra, edges with sixteen equivalent Sm(1)Sm8Ho4 cuboctahedra, faces with four equivalent Ho(1)Sm12 cuboctahedra, and faces with fourteen equivalent Sm(1)Sm8Ho4 cuboctahedra.
