There are a spread of Li–O bond distances ranging from 1.98–2.22 Å. In the ninth Li site, Li is bonded to four O atoms to form distorted LiO4 trigonal pyramids that share corners with eight LiO4 tetrahedra, corners with six equivalent LiO4 trigonal pyramids, an edgeedge with one FeO4 tetrahedra, and edges with three LiO4 tetrahedra. There are three shorter (1.99 Å) and one longer (2.19 Å) Li–O bond lengths. In the tenth Li site, Li is bonded to four O atoms to form LiO4 tetrahedra that share corners with two FeO4 tetrahedra, corners with six equivalent LiO4 tetrahedra, corners with four LiO4 trigonal pyramids, edges with two equivalent LiO4 tetrahedra, and edges with three LiO4 trigonal pyramids. There is one shorter (1.96 Å) and three longer (2.02 Å) Li–O bond length. There are two inequivalent Fe sites. In the first Fe site, Fe is bonded to four O atoms to form FeO4 tetrahedra that share corners with twelve LiO4 tetrahedra and edges with three LiO4 trigonal pyramids. There is three shorter (1.83 Å) and one longer (1.92 Å) Fe–O bond length. In the second Fe site, Fe is bonded to four O atoms to form FeO4 tetrahedra that share corners with twelve LiO4 tetrahedra and edges with three LiO4 trigonal pyramids. There is three shorter (1.84 Å) and one longer (1.93 Å) Fe–O bond length. There are eight inequivalent O sites. In the first O site, O is bonded to four Li and one Fe atom to form corner-sharing OLi4Fe trigonal bipyramids. In the second O site, O is bonded to four Li and one Fe atom to form corner-sharing OLi4Fe trigonal bipyramids. In the third O site, O is bonded in a 7-coordinate geometry to seven Li atoms.
