The crystal structure described by YNi3Ga2 crystallizes in the hexagonal P-6m2 space group. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded in a 18-coordinate geometry to six equivalent Ni(1), six equivalent Ni(2), and six equivalent Ga(2) atoms. In the second Y site, Y(2) is bonded in a 18-coordinate geometry to six equivalent Ni(1), six equivalent Ga(1), and six equivalent Ga(2) atoms. In the third Y site, Y(3) is bonded in a distorted hexagonal planar geometry to three equivalent Ni(2), twelve equivalent Ni(1), and three equivalent Ga(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 12-coordinate geometry to one Y(1), one Y(2), two equivalent Y(3), two equivalent Ni(1), two equivalent Ni(2), two equivalent Ga(1), and two equivalent Ga(2) atoms. In the second Ni site, Ni(2) is bonded in a 11-coordinate geometry to one Y(3), two equivalent Y(1), four equivalent Ni(1), two equivalent 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 11-coordinate geometry to one Y(3), two equivalent Y(2), two equivalent Ni(2), four equivalent Ni(1), and two equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 12-coordinate geometry to two equivalent Y(1), two equivalent Y(2), two equivalent Ni(2), four equivalent Ni(1), and two equivalent Ga(1) atoms. is represented by the CIF card [CIF]
