Li Li Ag As
Li2AgAs crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Li2AgAs clusters. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 2-coordinate geometry to one Li(2) and one As(1) atom. The Li(1)-Li(2) bond length is 1.56 Å. The Li(1)-As(1) bond length is 3.13 Å. In the second Li site, Li(2) is bonded in a single-bond geometry to one Li(1) atom. Ag(1) is bonded in a single-bond geometry to one As(1) atom. The Ag(1)-As(1) bond length is 0.53 Å. As(1) is bonded in a single-bond geometry to one Li(1) and one Ag(1) atom.
