Ce3Ga2 crystallizes in the tetragonal P4_2/mnm space group. There are three inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a distorted square co-planar geometry to four equivalent Ga(1) atoms. In the second Ce site, Ce(3) is bonded in a 6-coordinate geometry to six equivalent Ga(1) atoms. In the third Ce site, Ce(2) is bonded in a 6-coordinate geometry to six equivalent Ga(1) atoms. Ga(1) is bonded in a 10-coordinate geometry to two equivalent Ce(1), three equivalent Ce(2), three equivalent Ce(3), and two equivalent Ga(1) atoms.
Ce3Ga2 crystallizes in the tetragonal P4_2/mnm space group. There are three inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a distorted square co-planar geometry to four equivalent Ga(1) atoms. All Ce(1)-Ga(1) bond lengths are 3.36 Å. In the second Ce site, Ce(3) is bonded in a 6-coordinate geometry to six equivalent Ga(1) atoms. There are two shorter (3.06 Å) and four longer (3.09 Å) Ce(3)-Ga(1) bond lengths. In the third Ce site, Ce(2) is bonded in a 6-coordinate geometry to six equivalent Ga(1) atoms. There are two shorter (3.02 Å) and four longer (3.18 Å) Ce(2)-Ga(1) bond lengths. Ga(1) is bonded in a 10-coordinate geometry to two equivalent Ce(1), three equivalent Ce(2), three equivalent Ce(3), and two equivalent Ga(1) atoms. There is one shorter (2.85 Å) and one longer (2.91 Å) Ga(1)-Ga(1) bond length.
