Ce2(IrAl3)3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ce is bonded in a 11-coordinate geometry to six Ir and eleven Al atoms. There are four shorter (3.45 Å) and two longer (3.47 Å) Ce–Ir bond lengths. There are a spread of Ce–Al bond distances ranging from 3.06–3.18 Å. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 8-coordinate geometry to four equivalent Ce and eight Al atoms. There are a spread of Ir–Al bond distances ranging from 2.57–2.64 Å. In the second Ir site, Ir is bonded in a 8-coordinate geometry to four equivalent Ce and eight Al atoms. There are a spread of Ir–Al bond distances ranging from 2.56–2.63 Å. There are four inequivalent Al sites. In the first Al site, Al is bonded in a 2-coordinate geometry to two equivalent Ce and two equivalent Ir atoms. In the second Al site, Al is bonded in a 3-coordinate geometry to three equivalent Ce, three Ir, and one Al atom. The Al–Al bond length is 2.81 Å. In the third Al site, Al is bonded in a 3-coordinate geometry to two equivalent Ce, three Ir, and five Al atoms. There are one shorter (2.73 Å) and two longer (2.86 Å) Al–Al bond lengths. In the fourth Al site, Al is bonded in a 2-coordinate geometry to two equivalent Ce, two equivalent Ir, and two equivalent Al atoms.
