The material structure described by Dy3Ce 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 Ce(1) atoms to form DyCe4Dy8 cuboctahedra that share corners with twelve equivalent Dy(1)Ce4Dy8 cuboctahedra, edges with eight equivalent Dy(1)Ce4Dy8 cuboctahedra, edges with eight equivalent Dy(2)Ce4Dy8 cuboctahedra, edges with eight equivalent Ce(1)Dy12 cuboctahedra, faces with four equivalent Dy(2)Ce4Dy8 cuboctahedra, faces with four equivalent Ce(1)Dy12 cuboctahedra, and faces with ten equivalent Dy(1)Ce4Dy8 cuboctahedra. In the second Dy site, Dy(2) is bonded to eight equivalent Dy(1) and four equivalent Ce(1) atoms to form DyCe4Dy8 cuboctahedra that share corners with four equivalent Dy(2)Ce4Dy8 cuboctahedra, corners with eight equivalent Ce(1)Dy12 cuboctahedra, edges with eight equivalent Dy(2)Ce4Dy8 cuboctahedra, edges with sixteen equivalent Dy(1)Ce4Dy8 cuboctahedra, faces with four equivalent Dy(2)Ce4Dy8 cuboctahedra, faces with six equivalent Ce(1)Dy12 cuboctahedra, and faces with eight equivalent Dy(1)Ce4Dy8 cuboctahedra.
