The structure described by Dy3Nd is alpha La-derived structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to four equivalent Dy(1), four equivalent Dy(2), and four equivalent Nd(1) atoms to form DyNd4Dy8 cuboctahedra that share corners with twelve equivalent Dy(1)Nd4Dy8 cuboctahedra, edges with eight equivalent Dy(1)Nd4Dy8 cuboctahedra, edges with eight equivalent Dy(2)Nd4Dy8 cuboctahedra, edges with eight equivalent Nd(1)Dy12 cuboctahedra, faces with four equivalent Dy(2)Nd4Dy8 cuboctahedra, faces with four equivalent Nd(1)Dy12 cuboctahedra, and faces with ten equivalent Dy(1)Nd4Dy8 cuboctahedra. In the second Dy site, Dy(2) is bonded to eight equivalent Dy(1) and four equivalent Nd(1) atoms to form DyNd4Dy8 cuboctahedra that share corners with four equivalent Dy(2)Nd4Dy8 cuboctahedra, corners with eight equivalent Nd(1)Dy12 cuboctahedra, edges with eight equivalent Dy(2)Nd4Dy8 cuboctahedra, edges with sixteen equivalent Dy(1)Nd4Dy8 cuboctahedra, faces with four equivalent Dy(2)Nd4Dy8 cuboctahedra, faces with six equivalent Nd(1)Dy12 cuboctahedra, and faces with eight equivalent Dy(1)Nd4Dy8 cuboctahedra. Nd(1) is bonded to four equivalent Dy(2) and eight equivalent Dy(1) atoms to form NdDy12 cuboctahedra that share corners with four equivalent Nd(1)Dy12 cuboctahedra, corners with eight equivalent Dy(2)Nd4Dy8 cuboctahedra, edges with eight equivalent Nd(1)Dy12 cuboctahedra, edges with sixteen equivalent Dy(1)Nd4Dy8 cuboctahedra, faces with four equivalent Nd(1)Dy12 cuboctahedra, faces with six equivalent Dy(2)Nd4Dy8 cuboctahedra, and faces with eight equivalent Dy(1)Nd4Dy8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
