The crystal structure described by Ce2CuGa12 crystallizes in the tetragonal P4/nbm space group. Ce(1) is bonded in a 14-coordinate geometry to two equivalent Ga(1), four equivalent Ga(2), four equivalent Ga(3), and four equivalent Ga(4) atoms. Cu(1) is bonded in a body-centered cubic geometry to eight equivalent Ga(4) atoms. There are four inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 4-coordinate geometry to one Ce(1), one Ga(1), and two equivalent Ga(3) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to four equivalent Ce(1), one Ga(3), and four equivalent Ga(4) atoms. In the third Ga site, Ga(3) is bonded in a 9-coordinate geometry to four equivalent Ce(1), one Ga(2), and four equivalent Ga(1) atoms. In the fourth Ga site, Ga(4) is bonded in a 7-coordinate geometry to two equivalent Ce(1), two equivalent Cu(1), one Ga(4), and two equivalent Ga(2) atoms. is represented by the CIF file [CIF]
