MgWGa2 crystallizes in the triclinic P1 space group. Mg(1) is bonded in a 1-coordinate geometry to one W(1) and three equivalent Ga(2) atoms. The Mg(1)-W(1) bond length is 1.98 Å. There are a spread of Mg(1)-Ga(2) bond distances ranging from 2.30-3.10 Å. W(1) is bonded in a distorted bent 150 degrees geometry to one Mg(1), one Ga(1), and two equivalent Ga(2) atoms. The W(1)-Ga(1) bond length is 1.76 Å. There is one shorter (2.41 Å) and one longer (3.11 Å) W(1)-Ga(2) bond length. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted single-bond geometry to one W(1) and two equivalent Ga(2) atoms. There is one shorter (2.13 Å) and one longer (2.75 Å) Ga(1)-Ga(2) bond length. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to three equivalent Mg(1), two equivalent W(1), two equivalent Ga(1), and two equivalent Ga(2) atoms. Both Ga(2)-Ga(2) bond lengths are 2.77 Å.
