Li Li Al W
Li2WAl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Li2WAl cluster. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a single-bond geometry to one W(1) atom. The Li(1)-W(1) bond length is 1.32 Å. In the second Li site, Li(2) is bonded in a linear geometry to one W(1) and one Al(1) atom. The Li(2)-W(1) bond length is 1.32 Å. The Li(2)-Al(1) bond length is 1.51 Å. W(1) is bonded in a linear geometry to one Li(1) and one Li(2) atom. Al(1) is bonded in a distorted single-bond geometry to one Li(2) atom.
