The structure described by Li2AgF4 crystallizes in the trigonal R-3 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one F(1), one F(3), and two equivalent F(2) atoms to form corner-sharing LiF4 trigonal pyramids. In the second Li site, Li(2) is bonded to one F(1), one F(3), and two equivalent F(4) atoms to form corner-sharing LiF4 tetrahedra. Ag(1) is bonded in a distorted rectangular see-saw-like geometry to one F(1), one F(2), one F(3), and one F(4) atom. There are four inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal planar geometry to one Li(1), one Li(2), and one Ag(1) atom. In the second F site, F(2) is bonded in a 3-coordinate geometry to two equivalent Li(1) and one Ag(1) atom. In the third F site, F(3) is bonded in a distorted T-shaped geometry to one Li(1), one Li(2), and one Ag(1) atom. In the fourth F site, F(4) is bonded in a 3-coordinate geometry to two equivalent Li(2) and one Ag(1) atom. is represented by the CIF file [CIF]
