The material structure described by Y2NiGa3 crystallizes in the trigonal P3m1 space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 12-coordinate geometry to three equivalent Ni(1), three equivalent Ga(1), three equivalent Ga(2), and three equivalent Ga(3) atoms. In the second Y site, Y(2) is bonded in a 12-coordinate geometry to three equivalent Ni(1), three equivalent Ga(1), three equivalent Ga(2), and three equivalent Ga(3) atoms. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Y(1), three equivalent Y(2), and three equivalent Ga(1) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to three equivalent Y(1), three equivalent Y(2), and three equivalent Ni(1) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to three equivalent Y(1), three equivalent Y(2), and three equivalent Ga(3) atoms. In the third Ga site, Ga(3) is bonded in a 9-coordinate geometry to three equivalent Y(1), three equivalent Y(2), and three equivalent Ga(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
