The compound described by La2(NiGa)5 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 13-coordinate geometry to two equivalent Ni(1), two equivalent Ni(2), four equivalent Ni(3), one Ga(2), and four equivalent Ga(1) atoms. In the second La site, La(2) is bonded in a 13-coordinate geometry to one Ni(1), two equivalent Ni(3), four equivalent Ni(2), two equivalent Ga(2), and four equivalent Ga(1) atoms. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 11-coordinate geometry to one La(2), two equivalent La(1), two equivalent Ni(3), two equivalent Ga(2), and four equivalent Ga(1) atoms. In the second Ni site, Ni(2) is bonded in a 8-coordinate geometry to one La(1), two equivalent La(2), one Ga(2), and four equivalent Ga(1) atoms. In the third Ni site, Ni(3) is bonded in a 8-coordinate geometry to one La(2), two equivalent La(1), one Ni(1), and four equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to one La(1), one La(2), one Ni(1), two equivalent Ni(2), two equivalent Ni(3), one Ga(2), and two equivalent Ga(1) atoms. In the second Ga site, Ga(2) is bonded in a 11-coordinate geometry to one La(1), two equivalent La(2), two equivalent Ni(1), two equivalent Ni(2), and four equivalent Ga(1) atoms. is represented by the CIF card [CIF]
