LiGdS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Li(1) is bonded to six equivalent S(1) atoms to form LiS6 octahedra that share corners with six equivalent Gd(1)S6 octahedra, edges with six equivalent Li(1)S6 octahedra, and edges with six equivalent Gd(1)S6 octahedra. The corner-sharing octahedra are not tilted. Gd(1) is bonded to six equivalent S(1) atoms to form GdS6 octahedra that share corners with six equivalent Li(1)S6 octahedra, edges with six equivalent Li(1)S6 octahedra, and edges with six equivalent Gd(1)S6 octahedra. The corner-sharing octahedra are not tilted. S(1) is bonded to three equivalent Li(1) and three equivalent Gd(1) atoms to form a mixture of edge and corner-sharing SLi3Gd3 octahedra. The corner-sharing octahedra are not tilted.
