The material described by LiAgF2 crystallizes in the orthorhombic Pnma space group. Li(1) is bonded to one F(2) and three equivalent F(1) atoms to form LiF4 tetrahedra that share corners with seven equivalent Ag(1)F5 square pyramids, corners with two equivalent Li(1)F4 tetrahedra,  an edgeedge with one Ag(1)F5 square pyramid, and edges with two equivalent Li(1)F4 tetrahedra. Ag(1) is bonded to two equivalent F(1) and three equivalent F(2) atoms to form distorted AgF5 square pyramids that share corners with four equivalent Ag(1)F5 square pyramids, corners with seven equivalent Li(1)F4 tetrahedra, edges with two equivalent Ag(1)F5 square pyramids, and  an edgeedge with one Li(1)F4 tetrahedra. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 3-coordinate geometry to three equivalent Li(1) and two equivalent Ag(1) atoms. In the second F site, F(2) is bonded in a 4-coordinate geometry to one Li(1) and three equivalent Ag(1) atoms. is represented by the CIF file [CIF]
