The compound described by La2NiGa10 crystallizes in the tetragonal I4/mmm space group. La(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(2) atoms. There are four inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Ga(4) atoms. In the second Ga site, Ga(2) is bonded in a 7-coordinate geometry to two equivalent La(1), two equivalent Ni(1), one Ga(2), and two equivalent Ga(3) atoms. In the third Ga site, Ga(3) is bonded in a 9-coordinate geometry to four equivalent La(1), one Ga(4), and four equivalent Ga(2) atoms. In the fourth Ga site, Ga(4) is bonded in a 9-coordinate geometry to four equivalent La(1), one Ga(3), and four equivalent Ga(1) atoms. is represented by the CIF card [CIF]
