Ga Ga W Se
WGa2Se is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two WGa2Se clusters. W(1) is bonded in a distorted single-bond geometry to one Ga(2) and one Se(1) atom. The W(1)-Ga(2) bond length is 2.25 Å. The W(1)-Se(1) bond length is 0.51 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted single-bond geometry to one Se(1) atom. The Ga(1)-Se(1) bond length is 1.89 Å. In the second Ga site, Ga(2) is bonded in a distorted single-bond geometry to one W(1) atom. Se(1) is bonded in a 2-coordinate geometry to one W(1) and one Ga(1) atom.
