The structure described by La3Ni2Ga2 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 9-coordinate geometry to four equivalent Ni(1), two equivalent Ga(2), and three equivalent Ga(1) atoms. In the second La site, La(2) is bonded in a 9-coordinate geometry to four equivalent Ni(1), two equivalent Ga(1), and three equivalent Ga(2) atoms. Ni(1) is bonded in a 10-coordinate geometry to two equivalent La(1), four equivalent La(2), 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 La(1), four equivalent La(2), and two equivalent Ni(1) atoms. In the second Ga site, Ga(2) is bonded to two equivalent La(1), six equivalent La(2), and four equivalent Ni(1) atoms to form a mixture of distorted corner, edge, and face-sharing GaLa8Ni4 cuboctahedra. is represented by the CIF card [CIF]
