Materials Data on LiScS2 by Materials Project

Abstract

LiScS2 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 ScS6 octahedra, edges with six equivalent LiS6 octahedra, and edges with six equivalent ScS6 octahedra. The corner-sharing octahedral tilt angles are 2°. All Li–S bond lengths are 2.65 Å. Sc3+ is bonded to six equivalent S2- atoms to form ScS6 octahedra that share corners with six equivalent LiS6 octahedra, edges with six equivalent LiS6 octahedra, and edges with six equivalent ScS6 octahedra. The corner-sharing octahedral tilt angles are 2°. All Sc–S bond lengths are 2.58 Å. S2- is bonded to three equivalent Li1+ and three equivalent Sc3+ atoms to form a mixture of corner and edge-sharing SLi3Sc3 octahedra. The corner-sharing octahedral tilt angles are 0°.
