The material described by La3(Ni2Ga)2 crystallizes in the monoclinic C2/m space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 10-coordinate geometry to one Ni(1), five equivalent Ni(2), and four equivalent Ga(1) atoms. In the second La site, La(2) is bonded in a 2-coordinate geometry to two equivalent Ni(2), six equivalent Ni(1), and six equivalent Ga(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 10-coordinate geometry to one La(1), three equivalent La(2), one Ni(2), two equivalent Ni(1), and three equivalent Ga(1) atoms. In the second Ni site, Ni(2) is bonded in a 10-coordinate geometry to one La(2), five equivalent La(1), one Ni(1), one Ni(2), and two equivalent Ga(1) atoms. Ga(1) is bonded in a 12-coordinate geometry to three equivalent La(2), four equivalent La(1), two equivalent Ni(2), and three equivalent Ni(1) atoms. is represented by the CIF file [CIF]
