W2AgAl2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two W2AgAl2 clusters. W(1) is bonded in a 2-coordinate geometry to one W(1) and one Al(2) atom. The W(1)-W(1) bond length is 0.71 Å. The W(1)-Al(2) bond length is 1.03 Å. Ag(1) is bonded in a linear geometry to one Al(1) and one Al(2) atom. The Ag(1)-Al(1) bond length is 1.47 Å. The Ag(1)-Al(2) bond length is 1.74 Å. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a single-bond geometry to one Ag(1) atom. In the second Al site, Al(2) is bonded in a 3-coordinate geometry to two equivalent W(1) and one Ag(1) atom.
