The material described by CeIrIn crystallizes in the hexagonal P-62m space group. Ce(1) is bonded in a 11-coordinate geometry to one Ir(1), four equivalent Ir(2), and six equivalent In(1) atoms. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 9-coordinate geometry to three equivalent Ce(1) and six equivalent In(1) atoms. In the second Ir site, Ir(2) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three equivalent In(1) atoms. In(1) is bonded in a 10-coordinate geometry to six equivalent Ce(1), two equivalent Ir(1), and two equivalent Ir(2) atoms. is represented by the CIF card [CIF]
