Materials Data on Li2Fe2S3 by Materials Project
Li2Fe2S3 is Aluminum carbonitride-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded in a distorted see-saw-like geometry to four S2- atoms. There are a spread of Li–S bond distances ranging from 2.42–2.59 Å. Fe2+ is bonded to four S2- atoms to form a mixture of distorted edge and corner-sharing FeS4 tetrahedra. There are a spread of Fe–S bond distances ranging from 2.30–2.42 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded to two equivalent Li1+ and four equivalent Fe2+ atoms to form SLi2Fe4 octahedra that share corners with four equivalent SLi2Fe4 octahedra, corners with six equivalent SLi3Fe2 square pyramids, and edges with four equivalent SLi3Fe2 square pyramids. The corner-sharing octahedral tilt angles are 49°. In the second S2- site, S2- is bonded to three equivalent Li1+ and two equivalent Fe2+ atoms to form distorted SLi3Fe2 square pyramids that share corners with three equivalent SLi2Fe4 octahedra, corners with four equivalent SLi3Fe2 square pyramids, edges with two equivalent SLi2Fe4 octahedra, and edges with two equivalent SLi3Fe2 square pyramids. The corner-sharing octahedra tilt angles range from 44–75°.
