The material described by Ho3Dy is Copper-derived structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to four equivalent Ho(1), four equivalent Ho(2), and four equivalent Dy(1) atoms to form HoDy4Ho8 cuboctahedra that share corners with twelve equivalent Ho(1)Dy4Ho8 cuboctahedra, edges with eight equivalent Ho(1)Dy4Ho8 cuboctahedra, edges with eight equivalent Ho(2)Dy4Ho8 cuboctahedra, edges with eight equivalent Dy(1)Ho12 cuboctahedra, faces with four equivalent Ho(2)Dy4Ho8 cuboctahedra, faces with four equivalent Dy(1)Ho12 cuboctahedra, and faces with ten equivalent Ho(1)Dy4Ho8 cuboctahedra. In the second Ho site, Ho(2) is bonded to eight equivalent Ho(1) and four equivalent Dy(1) atoms to form HoDy4Ho8 cuboctahedra that share corners with four equivalent Ho(2)Dy4Ho8 cuboctahedra, corners with eight equivalent Dy(1)Ho12 cuboctahedra, edges with eight equivalent Ho(2)Dy4Ho8 cuboctahedra, edges with sixteen equivalent Ho(1)Dy4Ho8 cuboctahedra, faces with four equivalent Ho(2)Dy4Ho8 cuboctahedra, faces with six equivalent Dy(1)Ho12 cuboctahedra, and faces with eight equivalent Ho(1)Dy4Ho8 cuboctahedra. Dy(1) is bonded to four equivalent Ho(2) and eight equivalent Ho(1) atoms to form DyHo12 cuboctahedra that share corners with four equivalent Dy(1)Ho12 cuboctahedra, corners with eight equivalent Ho(2)Dy4Ho8 cuboctahedra, edges with eight equivalent Dy(1)Ho12 cuboctahedra, edges with sixteen equivalent Ho(1)Dy4Ho8 cuboctahedra, faces with four equivalent Dy(1)Ho12 cuboctahedra, faces with six equivalent Ho(2)Dy4Ho8 cuboctahedra, and faces with eight equivalent Ho(1)Dy4Ho8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
