Ce2CuGa3 crystallizes in the trigonal P3m1 space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to three equivalent Cu(1), three equivalent Ga(1), three equivalent Ga(2), and three equivalent Ga(3) atoms to form a mixture of distorted face and edge-sharing CeGa9Cu3 cuboctahedra. In the second Ce site, Ce(2) is bonded to three equivalent Cu(1), three equivalent Ga(1), three equivalent Ga(2), and three equivalent Ga(3) atoms to form a mixture of distorted face and edge-sharing CeGa9Cu3 cuboctahedra. Cu(1) is bonded in a 9-coordinate geometry to three equivalent Ce(1), three equivalent Ce(2), and three equivalent Ga(1) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to three equivalent Ce(1), three equivalent Ce(2), and three equivalent Cu(1) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to three equivalent Ce(1), three equivalent Ce(2), and three equivalent Ga(3) atoms. In the third Ga site, Ga(3) is bonded in a 9-coordinate geometry to three equivalent Ce(1), three equivalent Ce(2), and three equivalent Ga(2) atoms.
