The structure described by Er4PtCd crystallizes in the cubic F-43m space group. There are three inequivalent Er sites. In the first Er site, Er(1) is bonded in a 3-coordinate geometry to three equivalent Pt(1) and three equivalent Cd(1) atoms. In the second Er site, Er(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Pt(1) and two equivalent Cd(1) atoms. In the third Er site, Er(3) is bonded in a 4-coordinate geometry to two equivalent Pt(1) and two equivalent Cd(1) atoms. Pt(1) is bonded in a 6-coordinate geometry to three equivalent Er(1), three equivalent Er(2), and three equivalent Er(3) atoms. Cd(1) is bonded to three equivalent Er(1), three equivalent Er(2), three equivalent Er(3), and three equivalent Cd(1) atoms to form a mixture of distorted face and corner-sharing CdEr9Cd3 cuboctahedra. is represented by the CIF card [CIF]
