The structure described by DyLa3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. Dy(1) is bonded to four equivalent La(2) and eight equivalent La(1) atoms to form DyLa12 cuboctahedra that share corners with four equivalent Dy(1)La12 cuboctahedra, corners with eight equivalent La(2)La8Dy4 cuboctahedra, edges with eight equivalent Dy(1)La12 cuboctahedra, edges with sixteen equivalent La(1)La8Dy4 cuboctahedra, faces with four equivalent Dy(1)La12 cuboctahedra, faces with six equivalent La(2)La8Dy4 cuboctahedra, and faces with eight equivalent La(1)La8Dy4 cuboctahedra. There are two inequivalent La sites. In the first La site, La(1) is bonded to four equivalent Dy(1), four equivalent La(1), and four equivalent La(2) atoms to form LaLa8Dy4 cuboctahedra that share corners with twelve equivalent La(1)La8Dy4 cuboctahedra, edges with eight equivalent Dy(1)La12 cuboctahedra, edges with eight equivalent La(1)La8Dy4 cuboctahedra, edges with eight equivalent La(2)La8Dy4 cuboctahedra, faces with four equivalent Dy(1)La12 cuboctahedra, faces with four equivalent La(2)La8Dy4 cuboctahedra, and faces with ten equivalent La(1)La8Dy4 cuboctahedra. In the second La site, La(2) is bonded to four equivalent Dy(1) and eight equivalent La(1) atoms to form LaLa8Dy4 cuboctahedra that share corners with four equivalent La(2)La8Dy4 cuboctahedra, corners with eight equivalent Dy(1)La12 cuboctahedra, edges with eight equivalent La(2)La8Dy4 cuboctahedra, edges with sixteen equivalent La(1)La8Dy4 cuboctahedra, faces with four equivalent La(2)La8Dy4 cuboctahedra, faces with six equivalent Dy(1)La12 cuboctahedra, and faces with eight equivalent La(1)La8Dy4 cuboctahedra. is represented by the CIF card [CIF]
