The crystal structure described by Ce10Ga5Br4 crystallizes in the tetragonal I4/mcm space group. There are three inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 5-coordinate geometry to two equivalent Ga(2) and three equivalent Ga(1) atoms. In the second Ce site, Ce(2) is bonded in a 8-coordinate geometry to three equivalent Ga(1), two equivalent Br(1), and three equivalent Br(2) atoms. In the third Ce site, Ce(3) is bonded in a 6-coordinate geometry to one Ga(2), four equivalent Ga(1), and one Br(1) atom. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to two equivalent Ce(3), three equivalent Ce(1), three equivalent Ce(2), and one Ga(1) atom. In the second Ga site, Ga(2) is bonded in a distorted q6 geometry to two equivalent Ce(3) and eight equivalent Ce(1) atoms. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded to one Ce(3) and four equivalent Ce(2) atoms to form corner-sharing BrCe5 square pyramids. In the second Br site, Br(2) is bonded in a 6-coordinate geometry to six equivalent Ce(2) atoms. is represented by the CIF card [CIF]
