Materials Data on LiGdS2 by Materials Project
LiGdS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Li1+ is bonded to six equivalent S2- atoms to form LiS6 octahedra that share corners with six equivalent GdS6 octahedra, edges with six equivalent LiS6 octahedra, and edges with six equivalent GdS6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Li–S bond lengths are 2.76 Å. Gd3+ is bonded to six equivalent S2- atoms to form GdS6 octahedra that share corners with six equivalent LiS6 octahedra, edges with six equivalent LiS6 octahedra, and edges with six equivalent GdS6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Gd–S bond lengths are 2.76 Å. S2- is bonded to three equivalent Li1+ and three equivalent Gd3+ atoms to form a mixture of edge and corner-sharing SLi3Gd3 octahedra. The corner-sharing octahedral tilt angles are 0°.
