Tm4IrCd crystallizes in the cubic F-43m space group. There are three inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 3-coordinate geometry to three equivalent Ir(1) and three equivalent Cd(1) atoms. In the second Tm site, Tm(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ir(1) and two equivalent Cd(1) atoms. In the third Tm site, Tm(3) is bonded in a 4-coordinate geometry to two equivalent Ir(1) and two equivalent Cd(1) atoms. Ir(1) is bonded in a 6-coordinate geometry to three equivalent Tm(1), three equivalent Tm(2), and three equivalent Tm(3) atoms. Cd(1) is bonded to three equivalent Tm(1), three equivalent Tm(2), three equivalent Tm(3), and three equivalent Cd(1) atoms to form a mixture of distorted corner and face-sharing CdTm9Cd3 cuboctahedra.
