Fe4CdSn crystallizes in the trigonal R3m space group. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 6-coordinate geometry to one Fe(2), two equivalent Fe(1), one Cd(1), and two equivalent Sn(1) atoms. The Fe(1)-Fe(2) bond length is 1.99 Å. Both Fe(1)-Fe(1) bond lengths are 1.15 Å. The Fe(1)-Cd(1) bond length is 2.49 Å. There is one shorter (2.46 Å) and one longer (2.81 Å) Fe(1)-Sn(1) bond length. In the second Fe site, Fe(2) is bonded in a 9-coordinate geometry to three equivalent Fe(1), three equivalent Cd(1), and three equivalent Sn(1) atoms. All Fe(2)-Cd(1) bond lengths are 3.09 Å. All Fe(2)-Sn(1) bond lengths are 2.89 Å. Cd(1) is bonded in a 10-coordinate geometry to three equivalent Fe(1), three equivalent Fe(2), and four equivalent Sn(1) atoms. There is one shorter (2.83 Å) and three longer (3.15 Å) Cd(1)-Sn(1) bond lengths. Sn(1) is bonded in a 13-coordinate geometry to three equivalent Fe(2), six equivalent Fe(1), and four equivalent Cd(1) atoms.
