The structure described by Ce3(NiGa)2 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 4-coordinate geometry to four equivalent Ni(1), two equivalent Ga(1), and three equivalent Ga(2) atoms. In the second Ce site, Ce(2) is bonded in a 9-coordinate geometry to four equivalent Ni(1), two equivalent Ga(2), and three equivalent Ga(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), one Ni(1), one 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 9-coordinate geometry to three equivalent Ce(2), four equivalent Ce(1), and two equivalent Ni(1) atoms. In the second Ga site, Ga(2) is bonded to two equivalent Ce(2), six equivalent Ce(1), and four equivalent Ni(1) atoms to form a mixture of distorted edge, face, and corner-sharing GaCe8Ni4 cuboctahedra. is represented by the CIF card [CIF]
