The material described by Ce2NiGa10 crystallizes in the tetragonal I4/mmm space group. Ce(1) is bonded in a 16-coordinate geometry to four equivalent Ga(1), four equivalent Ga(2), four equivalent Ga(3), and four equivalent Ga(4) atoms. Ni(1) is bonded in a body-centered cubic geometry to eight equivalent Ga(3) atoms. There are four inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), one Ga(4), and four equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded to four equivalent Ce(1), four equivalent Ga(1), and four equivalent Ga(2) atoms to form a mixture of distorted corner and face-sharing GaCe4Ga8 cuboctahedra. In the third Ga site, Ga(3) is bonded in a 7-coordinate geometry to two equivalent Ce(1), two equivalent Ni(1), one Ga(3), and two equivalent Ga(4) atoms. In the fourth Ga site, Ga(4) is bonded in a 9-coordinate geometry to four equivalent Ce(1), one Ga(1), and four equivalent Ga(3) atoms. is represented by the CIF file [CIF]
