Dy3Y is Copper-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 Y(1) atoms to form DyDy8Y4 cuboctahedra that share corners with twelve equivalent Dy(1)Dy8Y4 cuboctahedra, edges with eight equivalent Dy(1)Dy8Y4 cuboctahedra, edges with eight equivalent Dy(2)Dy8Y4 cuboctahedra, edges with eight equivalent Y(1)Dy12 cuboctahedra, faces with four equivalent Dy(2)Dy8Y4 cuboctahedra, faces with four equivalent Y(1)Dy12 cuboctahedra, and faces with ten equivalent Dy(1)Dy8Y4 cuboctahedra. In the second Dy site, Dy(2) is bonded to eight equivalent Dy(1) and four equivalent Y(1) atoms to form DyDy8Y4 cuboctahedra that share corners with four equivalent Dy(2)Dy8Y4 cuboctahedra, corners with eight equivalent Y(1)Dy12 cuboctahedra, edges with eight equivalent Dy(2)Dy8Y4 cuboctahedra, edges with sixteen equivalent Dy(1)Dy8Y4 cuboctahedra, faces with four equivalent Dy(2)Dy8Y4 cuboctahedra, faces with six equivalent Y(1)Dy12 cuboctahedra, and faces with eight equivalent Dy(1)Dy8Y4 cuboctahedra. Y(1) is bonded to four equivalent Dy(2) and eight equivalent Dy(1) atoms to form YDy12 cuboctahedra that share corners with four equivalent Y(1)Dy12 cuboctahedra, corners with eight equivalent Dy(2)Dy8Y4 cuboctahedra, edges with eight equivalent Y(1)Dy12 cuboctahedra, edges with sixteen equivalent Dy(1)Dy8Y4 cuboctahedra, faces with four equivalent Y(1)Dy12 cuboctahedra, faces with six equivalent Dy(2)Dy8Y4 cuboctahedra, and faces with eight equivalent Dy(1)Dy8Y4 cuboctahedra.
