The material structure described by CeIrP is hexagonal omega structure-derived structured and crystallizes in the tetragonal I4_1md space group. Ce(1) is bonded to six Ir(1,1) and six equivalent P(1) atoms to form a mixture of face and edge-sharing CeP6Ir6 cuboctahedra. There are three inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three equivalent P(1) atoms. In the second Ir site, Ir(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three equivalent P(1) atoms. In the third Ir site, Ir(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three equivalent P(1) atoms. P(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three Ir(1,1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
