The crystal structure described by Lu2Ni14Ga3 crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 18-coordinate geometry to six equivalent Ni(2) and twelve equivalent Ni(3) atoms. In the second Lu site, Lu(2) is bonded in a 20-coordinate geometry to two equivalent Ni(1), six equivalent Ni(2), six equivalent Ni(3), and six equivalent Ga(1) atoms. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 14-coordinate geometry to one Lu(2), one Ni(1), three equivalent Ni(3), six equivalent Ni(2), and three equivalent Ga(1) atoms. In the second Ni site, Ni(2) is bonded in a 12-coordinate geometry to one Lu(1), one Lu(2), two equivalent Ni(1), two equivalent Ni(2), four equivalent Ni(3), and two equivalent Ga(1) atoms. In the third Ni site, Ni(3) is bonded in a 12-coordinate geometry to one Lu(2), two equivalent Lu(1), one Ni(1), two equivalent Ni(3), four equivalent Ni(2), and two equivalent Ga(1) atoms. Ga(1) is bonded to two equivalent Lu(2), two equivalent Ni(1), four equivalent Ni(2), and four equivalent Ni(3) atoms to form a mixture of distorted face and corner-sharing GaLu2Ni10 cuboctahedra. is represented by the CIF file [CIF]
