The material described by LiAg2F4 crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded to one F(1), one F(2), one F(3), and one F(4) atom to form LiF4 tetrahedra that share corners with five equivalent Ag(2)F5 trigonal bipyramids. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a rectangular see-saw-like geometry to one F(2), one F(4), and two equivalent F(1) atoms. In the second Ag site, Ag(2) is bonded to one F(1), one F(2), one F(4), and two equivalent F(3) atoms to form AgF5 trigonal bipyramids that share corners with five equivalent Li(1)F4 tetrahedra and  an edgeedge with one Ag(2)F5 trigonal bipyramid. There are four inequivalent F sites. In the first F site, F(1) is bonded to one Li(1), one Ag(2), and two equivalent Ag(1) atoms to form distorted corner-sharing FLiAg3 tetrahedra. In the second F site, F(2) is bonded in a distorted trigonal planar geometry to one Li(1), one Ag(1), and one Ag(2) atom. In the third F site, F(3) is bonded in a distorted trigonal non-coplanar geometry to one Li(1) and two equivalent Ag(2) atoms. In the fourth F site, F(4) is bonded in a 3-coordinate geometry to one Li(1), one Ag(1), and one Ag(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
