LiCoF2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Li(1) is bonded to six equivalent F(1) atoms to form LiF6 octahedra that share corners with six equivalent Co(1)F6 octahedra, edges with six equivalent Li(1)F6 octahedra, and edges with six equivalent Co(1)F6 octahedra. The corner-sharing octahedral tilt angles are 9°. Co(1) is bonded to six equivalent F(1) atoms to form distorted CoF6 octahedra that share corners with six equivalent Li(1)F6 octahedra, edges with six equivalent Li(1)F6 octahedra, and edges with six equivalent Co(1)F6 octahedra. The corner-sharing octahedral tilt angles are 9°. F(1) is bonded to three equivalent Li(1) and three equivalent Co(1) atoms to form a mixture of edge and corner-sharing FLi3Co3 octahedra. The corner-sharing octahedra are not tilted.
