Abstract

Li3Fe2S4 is Aluminum carbonitride-like structured and 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 trigonal bipyramids that share corners with six equivalent FeS4 tetrahedra, corners with two equivalent LiS5 trigonal bipyramids, corners with four equivalent LiS4 trigonal pyramids, edges with two equivalent FeS4 tetrahedra, and edges with two equivalent LiS4 trigonal pyramids. There are a spread of Li–S bond distances ranging from 2.45–3.01 Å. In the second Li1+ site, Li1+ is bonded to four S2- atoms to form distorted LiS4 trigonal pyramids that share corners with six equivalent FeS4 tetrahedra, corners with two equivalent LiS5 trigonal bipyramids, corners with five equivalent LiS4 trigonal pyramids, an edgeedge with one FeS4 tetrahedra, an edgeedge with one LiS5 trigonal bipyramid, and an edgeedge with one LiS4 trigonal pyramid. There are a spread of Li–S bond distances ranging from 2.46–2.64 Å. Fe+2.50+ is bonded to four S2- atoms to form FeS4 tetrahedra that share corners with three equivalent LiS5 trigonal bipyramids, corners with six equivalent LiS4 trigonal pyramids, edges with two equivalent FeS4 tetrahedra, an edgeedge with one LiS5more »« less
