Li2AgF4 crystallizes in the monoclinic P2/c space group. Li(1) is bonded to two equivalent F(1) and two equivalent F(2) atoms to form LiF4 tetrahedra that share corners with six equivalent Ag(1)F6 octahedra, corners with two equivalent Li(1)F4 tetrahedra, and  an edgeedge with one Li(1)F4 tetrahedra. The corner-sharing octahedral tilt angles range from 42-84°. Ag(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form AgF6 octahedra that share corners with twelve equivalent Li(1)F4 tetrahedra and edges with two equivalent Ag(1)F6 octahedra. There are two inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to two equivalent Li(1) and one Ag(1) atom. In the second F site, F(2) is bonded in a distorted see-saw-like geometry to two equivalent Li(1) and two equivalent Ag(1) atoms.

The corner-sharing octahedral tilt angles range from 42-84°. There is one shorter (1.92 Å) and one longer (1.94 Å) Li(1)-F(1) bond length. There is one shorter (1.93 Å) and one longer (2.00 Å) Li(1)-F(2) bond length. Ag(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form AgF6 octahedra that share corners with twelve equivalent Li(1)F4 tetrahedra and edges with two equivalent Ag(1)F6 octahedra. Both Ag(1)-F(1) bond lengths are 2.10 Å. There are two shorter (2.38 Å) and two longer (2.39 Å) Ag(1)-F(2) bond lengths. There are two inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to two equivalent Li(1) and one Ag(1) atom. In the second F site, F(2) is bonded in a distorted see-saw-like geometry to two equivalent Li(1) and two equivalent Ag(1) atoms.
