The structure described by Ce2CoGa9Ge2 crystallizes in the tetragonal P4/nmm space group. Ce(1) is bonded in a 14-coordinate geometry to two equivalent Ga(3), four equivalent Ga(1), four equivalent Ga(2), two equivalent Ge(1), and two equivalent Ge(2) atoms. Co(1) is bonded in a body-centered cubic geometry to eight 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 two equivalent Ce(1), two equivalent Co(1), three equivalent Ga(1), one Ge(1), and one Ge(2) atom. In the second Ga site, Ga(2) is bonded in a 6-coordinate geometry to two equivalent Ce(1), one Ga(3), and three equivalent Ga(2) atoms. In the third Ga site, Ga(3) is bonded in a 9-coordinate geometry to four equivalent Ce(1), four equivalent Ga(2), and one Ge(1) atom. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), one Ga(3), and four equivalent Ga(1) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Ga(1) atoms. is represented by the CIF file [CIF]
