The structure described by ErCu4Cd is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Er(1) is bonded in a 16-coordinate geometry to twelve equivalent Cu(1) and four equivalent Cd(1) atoms. Cu(1) is bonded to three equivalent Er(1), six equivalent Cu(1), and three equivalent Cd(1) atoms to form a mixture of corner, edge, and face-sharing CuEr3Cd3Cu6 cuboctahedra. Cd(1) is bonded in a 16-coordinate geometry to four equivalent Er(1) and twelve equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
