LiAg2F4 crystallizes in the orthorhombic Pnma space group. Li(1) is bonded to one F(2), one F(3), and two equivalent F(1) atoms to form LiF4 tetrahedra that share corners with six equivalent Ag(1)F6 octahedra and corners with four equivalent Ag(2)F4 tetrahedra. The corner-sharing octahedral tilt angles range from 46-59°. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form AgF6 octahedra that share corners with six equivalent Li(1)F4 tetrahedra, corners with six equivalent Ag(2)F4 tetrahedra, and edges with two equivalent Ag(1)F6 octahedra. In the second Ag site, Ag(2) is bonded to one F(2), one F(3), and two equivalent F(1) atoms to form AgF4 tetrahedra that share corners with six equivalent Ag(1)F6 octahedra and corners with four equivalent Li(1)F4 tetrahedra. The corner-sharing octahedral tilt angles range from 72-75°. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal planar geometry to one Li(1), one Ag(1), and one Ag(2) atom. In the second F site, F(2) is bonded to one Li(1), one Ag(2), and two equivalent Ag(1) atoms to form a mixture of distorted edge and corner-sharing FLiAg3 tetrahedra. In the third F site, F(3) is bonded to one Li(1), one Ag(2), and two equivalent Ag(1) atoms to form a mixture of distorted edge and corner-sharing FLiAg3 tetrahedra.
