LiAg2Si crystallizes in the cubic F-43m space group. Li(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ag(2), six equivalent Ag(1), and four equivalent Si(1) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 14-coordinate geometry to six equivalent Li(1), four equivalent Ag(2), and four equivalent Si(1) atoms. In the second Ag site, Ag(2) is bonded to four equivalent Li(1) and four equivalent Ag(1) atoms to form distorted edge-sharing AgLi4Ag4 tetrahedra. Si(1) is bonded in a distorted body-centered cubic geometry to four equivalent Li(1) and four equivalent Ag(1) atoms.
