Li2LaAg is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Li2LaAg clusters. Li(1) is bonded in a 3-coordinate geometry to one Li(1), one La(1), and one Ag(1) atom. The Li(1)-Li(1) bond length is 0.95 Å. The Li(1)-La(1) bond length is 1.86 Å. The Li(1)-Ag(1) bond length is 1.86 Å. La(1) is bonded in a single-bond geometry to two equivalent Li(1) and one Ag(1) atom. The La(1)-Ag(1) bond length is 0.95 Å. Ag(1) is bonded in a single-bond geometry to two equivalent Li(1) and one La(1) atom.
