Li3Ag2Ge3 crystallizes in the cubic Pn-3m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to four equivalent Ag(1) atoms to form distorted corner-sharing LiAg4 tetrahedra. In the second Li site, Li(2) is bonded in a 6-coordinate geometry to six equivalent Ag(1) and six equivalent Ge(1) atoms. Ag(1) is bonded in a 14-coordinate geometry to two equivalent Li(1), six equivalent Li(2), and six equivalent Ge(1) atoms. Ge(1) is bonded in a distorted body-centered cubic geometry to four equivalent Li(2) and four equivalent Ag(1) atoms.
