LiAg3 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LiAg3 clusters. Li(1) is bonded in a 2-coordinate geometry to two equivalent Ag(1) atoms. Both Li(1)-Ag(1) bond lengths are 0.29 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 2-coordinate geometry to one Li(1), one Ag(1), and one Ag(2) atom. The Ag(1)-Ag(1) bond length is 0.18 Å. The Ag(1)-Ag(2) bond length is 0.50 Å. In the second Ag site, Ag(2) is bonded in a 2-coordinate geometry to two equivalent Ag(1) atoms.
