WGa2As is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one WGa2As cluster. W(1) is bonded in a single-bond geometry to one Ga(1), one Ga(2), and one As(1) atom. The W(1)-Ga(1) bond length is 0.22 Å. The W(1)-Ga(2) bond length is 0.89 Å. The W(1)-As(1) bond length is 0.61 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a single-bond geometry to one W(1), one Ga(2), and one As(1) atom. The Ga(1)-Ga(2) bond length is 0.89 Å. The Ga(1)-As(1) bond length is 0.61 Å. In the second Ga site, Ga(2) is bonded in a distorted single-bond geometry to one W(1) and one Ga(1) atom. As(1) is bonded in a 2-coordinate geometry to one W(1) and one Ga(1) atom.
