Abstract

Li3Fe2S4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to five S2- atoms to form distorted LiS5 square pyramids that share corners with four equivalent LiS6 octahedra, corners with two equivalent LiS5 square pyramids, corners with six equivalent FeS4 tetrahedra, an edgeedge with one LiS6 octahedra, edges with two equivalent LiS5 square pyramids, edges with two equivalent FeS4 tetrahedra, and a faceface with one LiS5 square pyramid. The corner-sharing octahedra tilt angles range from 33–78°. There are a spread of Li–S bond distances ranging from 2.55–2.87 Å. In the second Li1+ site, Li1+ is bonded to six S2- atoms to form distorted LiS6 octahedra that share corners with eight equivalent LiS5 square pyramids, corners with eight equivalent FeS4 tetrahedra, edges with two equivalent LiS5 square pyramids, edges with two equivalent FeS4 tetrahedra, and faces with two equivalent LiS6 octahedra. There are a spread of Li–S bond distances ranging from 2.49–2.98 Å. Fe+2.50+ is bonded to four S2- atoms to form FeS4 tetrahedra that share corners with four equivalent LiS6 octahedra, corners with six equivalent LiS5 square pyramids, an edgeedge with one LiS6 octahedra,more »« less
