The crystal structure described by CeNi3Ga2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 18-coordinate geometry to three equivalent Ni(2), six equivalent Ni(1), three equivalent Ga(2), and six equivalent Ga(1) atoms. In the second Ce site, Ce(2) is bonded in a distorted hexagonal planar geometry to six equivalent Ni(1), six equivalent Ni(2), and six equivalent Ga(2) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 11-coordinate geometry to one Ce(2), two equivalent Ce(1), two equivalent Ni(1), two equivalent Ni(2), two equivalent Ga(1), and two equivalent Ga(2) atoms. In the second Ni site, Ni(2) is bonded in a 12-coordinate geometry to two equivalent Ce(1), two equivalent Ce(2), four equivalent Ni(1), two equivalent Ga(1), and two equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 12-coordinate geometry to four equivalent Ce(1), two equivalent Ni(2), four equivalent Ni(1), and two equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 12-coordinate geometry to two equivalent Ce(1), two equivalent Ce(2), two equivalent Ni(2), four equivalent Ni(1), and two equivalent Ga(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
