The material structure described by Hf2NiGa3 crystallizes in the monoclinic Cm space group. There are two inequivalent Hf sites. In the first Hf site, Hf(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 Hf site, Hf(2) is bonded in a 11-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 10-coordinate geometry to three equivalent Hf(1), three equivalent Hf(2), one Ga(1), one Ga(3), and two equivalent Ga(2) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to three equivalent Hf(1), three equivalent Hf(2), one Ni(1), one Ga(2), and two equivalent Ga(3) atoms. In the second Ga site, Ga(2) is bonded in a 10-coordinate geometry to three equivalent Hf(1), three equivalent Hf(2), two equivalent Ni(1), one Ga(1), and one Ga(3) atom. In the third Ga site, Ga(3) is bonded in a 10-coordinate geometry to three equivalent Hf(1), three equivalent Hf(2), one Ni(1), one Ga(2), and two equivalent Ga(1) atoms. is represented by the CIF file [CIF]
