The structure described by LiAgF2 crystallizes in the orthorhombic Pna2_1 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 four equivalent Li(1)F4 tetrahedra and corners with eight equivalent Ag(1)F4 tetrahedra. Ag(1) is bonded to two equivalent F(1) and two equivalent F(2) atoms to form AgF4 tetrahedra that share corners with four equivalent Ag(1)F4 tetrahedra and corners with eight equivalent Li(1)F4 tetrahedra. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 4-coordinate geometry to two equivalent Li(1) and two equivalent Ag(1) atoms. In the second F site, F(2) is bonded to two equivalent Li(1) and two equivalent Ag(1) atoms to form distorted corner-sharing FLi2Ag2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
