LiAg2F6 is Hydrophilite-derived structured and crystallizes in the tetragonal P-42_1m space group. Li(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form LiF6 octahedra that share corners with four equivalent Ag(1)F6 octahedra, corners with four equivalent Ag(2)F6 octahedra,  an edgeedge with one Ag(1)F6 octahedra, and  an edgeedge with one Ag(2)F6 octahedra. The corner-sharing octahedral tilt angles range from 50-53°. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to two equivalent F(3) and four equivalent F(2) atoms to form AgF6 octahedra that share corners with four equivalent Li(1)F6 octahedra, corners with four equivalent Ag(1)F6 octahedra,  an edgeedge with one Li(1)F6 octahedra, and  an edgeedge with one Ag(2)F6 octahedra. The corner-sharing octahedral tilt angles range from 50-53°. In the second Ag site, Ag(2) is bonded to two equivalent F(3) and four equivalent F(1) atoms to form AgF6 octahedra that share corners with four equivalent Li(1)F6 octahedra, corners with four equivalent Ag(2)F6 octahedra,  an edgeedge with one Li(1)F6 octahedra, and  an edgeedge with one Ag(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 50-53°. There are three inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to one Li(1) and two equivalent Ag(2) atoms. In the second F site, F(2) is bonded in a trigonal planar geometry to one Li(1) and two equivalent Ag(1) atoms. In the third F site, F(3) is bonded in a distorted trigonal planar geometry to one Li(1), one Ag(1), and one Ag(2) atom.
