Tb4IrIn 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 Ir(1) and three equivalent In(1) atoms. In the second Tb site, Tb(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ir(1) and two equivalent In(1) atoms. In the third Tb site, Tb(3) is bonded in a 4-coordinate geometry to two equivalent Ir(1) and two equivalent In(1) atoms. Ir(1) is bonded in a 6-coordinate geometry to three equivalent Tb(1), three equivalent Tb(2), and three equivalent Tb(3) atoms. In(1) is bonded in a 12-coordinate geometry to three equivalent Tb(1), three equivalent Tb(2), three equivalent Tb(3), and three equivalent In(1) atoms.
