The compound described by Lu3Dy crystallizes in the hexagonal P6_3/mmc space group. Lu(1) is bonded to eight equivalent Lu(1) and four equivalent Dy(1) atoms to form LuDy4Lu8 cuboctahedra that share corners with four equivalent Dy(1)Lu12 cuboctahedra, corners with fourteen equivalent Lu(1)Dy4Lu8 cuboctahedra, edges with six equivalent Dy(1)Lu12 cuboctahedra, edges with twelve equivalent Lu(1)Dy4Lu8 cuboctahedra, faces with four equivalent Dy(1)Lu12 cuboctahedra, and faces with sixteen equivalent Lu(1)Dy4Lu8 cuboctahedra. Dy(1) is bonded to twelve equivalent Lu(1) atoms to form DyLu12 cuboctahedra that share corners with six equivalent Dy(1)Lu12 cuboctahedra, corners with twelve equivalent Lu(1)Dy4Lu8 cuboctahedra, edges with eighteen equivalent Lu(1)Dy4Lu8 cuboctahedra, faces with eight equivalent Dy(1)Lu12 cuboctahedra, and faces with twelve equivalent Lu(1)Dy4Lu8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
