The compound described by YbDy3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. Yb(1) is bonded to four equivalent Dy(2) and eight equivalent Dy(1) atoms to form YbDy12 cuboctahedra that share corners with four equivalent Yb(1)Dy12 cuboctahedra, corners with eight equivalent Dy(2)Yb4Dy8 cuboctahedra, edges with eight equivalent Yb(1)Dy12 cuboctahedra, edges with sixteen equivalent Dy(1)Yb4Dy8 cuboctahedra, faces with four equivalent Yb(1)Dy12 cuboctahedra, faces with six equivalent Dy(2)Yb4Dy8 cuboctahedra, and faces with eight equivalent Dy(1)Yb4Dy8 cuboctahedra. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to four equivalent Yb(1), four equivalent Dy(1), and four equivalent Dy(2) atoms to form DyYb4Dy8 cuboctahedra that share corners with twelve equivalent Dy(1)Yb4Dy8 cuboctahedra, edges with eight equivalent Yb(1)Dy12 cuboctahedra, edges with eight equivalent Dy(1)Yb4Dy8 cuboctahedra, edges with eight equivalent Dy(2)Yb4Dy8 cuboctahedra, faces with four equivalent Yb(1)Dy12 cuboctahedra, faces with four equivalent Dy(2)Yb4Dy8 cuboctahedra, and faces with ten equivalent Dy(1)Yb4Dy8 cuboctahedra. In the second Dy site, Dy(2) is bonded to four equivalent Yb(1) and eight equivalent Dy(1) atoms to form DyYb4Dy8 cuboctahedra that share corners with four equivalent Dy(2)Yb4Dy8 cuboctahedra, corners with eight equivalent Yb(1)Dy12 cuboctahedra, edges with eight equivalent Dy(2)Yb4Dy8 cuboctahedra, edges with sixteen equivalent Dy(1)Yb4Dy8 cuboctahedra, faces with four equivalent Dy(2)Yb4Dy8 cuboctahedra, faces with six equivalent Yb(1)Dy12 cuboctahedra, and faces with eight equivalent Dy(1)Yb4Dy8 cuboctahedra. is represented by the CIF file [CIF]
