The material described by Ce10Ga5Cl4 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 6-coordinate geometry to one Ga(1), four equivalent Ga(2), and one Cl(2) atom. In the second Ce site, Ce(2) is bonded in a 5-coordinate geometry to two equivalent Ga(1) and three equivalent Ga(2) atoms. In the third Ce site, Ce(3) is bonded in a 8-coordinate geometry to three equivalent Ga(2), two equivalent Cl(2), and three equivalent Cl(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted q6 geometry to two equivalent Ce(1) and eight equivalent Ce(2) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to two equivalent Ce(1), three equivalent Ce(2), three equivalent Ce(3), and one Ga(2) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(2) is bonded to one Ce(1) and four equivalent Ce(3) atoms to form ClCe5 square pyramids that share corners with four equivalent Cl(1)Ce6 pentagonal pyramids, corners with four equivalent Cl(2)Ce5 square pyramids, and edges with four equivalent Cl(1)Ce6 pentagonal pyramids. In the second Cl site, Cl(1) is bonded to six equivalent Ce(3) atoms to form distorted ClCe6 pentagonal pyramids that share corners with four equivalent Cl(2)Ce5 square pyramids, edges with four equivalent Cl(1)Ce6 pentagonal pyramids, edges with four equivalent Cl(2)Ce5 square pyramids, and  a faceface with one Cl(1)Ce6 pentagonal pyramid. is represented by the CIF file [CIF]
