The structure described by Tb4PtCd crystallizes in the cubic F-43m space group. There are three inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 3-coordinate geometry to three equivalent Pt(1) and three equivalent Cd(1) atoms. In the second Tb site, Tb(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Pt(1) and two equivalent Cd(1) atoms. In the third Tb site, Tb(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 Tb(1), three equivalent Tb(2), and three equivalent Tb(3) atoms. Cd(1) is bonded to three equivalent Tb(1), three equivalent Tb(2), three equivalent Tb(3), and three equivalent Cd(1) atoms to form a mixture of distorted face and corner-sharing CdTb9Cd3 cuboctahedra. is represented by the CIF file [CIF]
