The material described by Li2AgF3 is Caswellsilverite-like structured and crystallizes in the trigonal P-3m1 space group. Li(1) is bonded to three equivalent F(1) and three equivalent F(2) atoms to form a mixture of corner and edge-sharing LiF6 octahedra. The corner-sharing octahedra are not tilted. Ag(1) is bonded in a 6-coordinate geometry to six equivalent F(1) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded to three equivalent Li(1) and three equivalent Ag(1) atoms to form distorted FLi3Ag3 octahedra that share corners with three equivalent F(1)Li3Ag3 octahedra, corners with three equivalent F(2)Li6 octahedra, edges with three equivalent F(2)Li6 octahedra, and edges with nine equivalent F(1)Li3Ag3 octahedra. The corner-sharing octahedral tilt angles range from 0-1°. In the second F site, F(2) is bonded to six equivalent Li(1) atoms to form FLi6 octahedra that share corners with six equivalent F(1)Li3Ag3 octahedra, edges with six equivalent F(1)Li3Ag3 octahedra, and edges with six equivalent F(2)Li6 octahedra. The corner-sharing octahedral tilt angles are 1°. is represented by the CIF file [CIF]
