WNi2Ga crystallizes in the monoclinic Cm space group. W(1) is bonded in a 2-coordinate geometry to one Ni(1) and one Ni(2) atom. The W(1)-Ni(1) bond length is 1.78 Å. The W(1)-Ni(2) bond length is 1.78 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 1-coordinate geometry to one W(1) and one Ga(1) atom. The Ni(1)-Ga(1) bond length is 2.85 Å. In the second Ni site, Ni(2) is bonded in a distorted single-bond geometry to one W(1) and three equivalent Ga(1) atoms. There is one shorter (2.56 Å) and two longer (2.95 Å) Ni(2)-Ga(1) bond lengths. Ga(1) is bonded in a 8-coordinate geometry to one Ni(1), three equivalent Ni(2), and four equivalent Ga(1) atoms. All Ga(1)-Ga(1) bond lengths are 2.71 Å.
