Abstract

Li2Fe5Si5O16 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share corners with two equivalent FeO4 tetrahedra and corners with six SiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.89–2.65 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two equivalent FeO4 tetrahedra and corners with six SiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.91–2.36 Å. There are five inequivalent Fe2+ sites.
