The material described by Li2AgF4 crystallizes in the tetragonal P4/ncc space group. Li(1) is bonded to four equivalent F(1) atoms to form distorted edge-sharing LiF4 tetrahedra. Ag(1) is bonded in a rectangular see-saw-like geometry to four equivalent F(1) atoms. F(1) is bonded in a trigonal non-coplanar geometry to two equivalent Li(1) and one Ag(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
