description: LiFeP3H8O13 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with two equivalent PO4 tetrahedra and edges with two equivalent FeO7 pentagonal bipyramids. There are a spread of Li–O bond distances ranging from 2.11–2.17 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with four PO4 tetrahedra and edges with two equivalent FeO7 pentagonal bipyramids. There are a spread of Li–O bond distances ranging from 2.04–2.29 Å. Fe2+ is bonded to seven O2- atoms to form distorted FeO7 pentagonal bipyramids that share corners with five PO4 tetrahedra and edges with two LiO6 octahedra.
