Title: Materials Data on Li2FeCo3O8 by Materials Project

Abstract

Li2FeCo3O8 is Spinel-derived structured and crystallizes in the monoclinic Cc 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 LiO4 tetrahedra that share corners with three equivalent FeO6 octahedra and corners with nine CoO6 octahedra. The corner-sharing octahedra tilt angles range from 57–64°. There are a spread of Li–O bond distances ranging from 1.92–2.00 Å. In the second Li1+ site, Li1+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.77–1.92 Å. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six CoO6 octahedra, corners with three equivalent LiO4 tetrahedra, and edges with three CoO6 octahedra. The corner-sharing octahedra tilt angles range from 49–54°. There are a spread of Fe–O bond distances ranging from 1.99–2.12 Å. There are three inequivalent Co+3.67+ sites. In the first Co+3.67+ site, Co+3.67+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent FeO6 octahedra, corners with three equivalent LiO4 tetrahedra, an edgeedge with one FeO6 octahedra, and edges with four CoO6 octahedra.

In the second Co+3.67+ site, Co+3.67+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent FeO6 octahedra, corners with three equivalent LiO4 tetrahedra, an edgeedge with one FeO6 octahedra, and edges with four CoO6 octahedra. The corner-sharing octahedra tilt angles range from 50–53°. There are a spread of Co–O bond distances ranging from 1.89–1.92 Å. In the third Co+3.67+ site, Co+3.67+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent FeO6 octahedra, corners with three equivalent LiO4 tetrahedra, an edgeedge with one FeO6 octahedra, and edges with four CoO6 octahedra. The corner-sharing octahedra tilt angles range from 49–52°. There are a spread of Co–O bond distances ranging from 1.87–1.92 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, one Fe3+, and two Co+3.67+ atoms. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+, one Fe3+, and two Co+3.67+ atoms. In the third O2- site, O2- is bonded to one Li1+, one Fe3+, and two Co+3.67+ atoms to form distorted OLiFeCo2 tetrahedra that share corners with four OLiCo3 tetrahedra and edges with two OLiFeCo2 tetrahedra. In the fourth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+ and three Co+3.67+ atoms. In the fifth O2- site, O2- is bonded to one Li1+ and three Co+3.67+ atoms to form distorted corner-sharing OLiCo3 tetrahedra. In the sixth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, one Fe3+, and two Co+3.67+ atoms. In the seventh O2- site, O2- is bonded to one Li1+, one Fe3+, and two Co+3.67+ atoms to form a mixture of distorted edge and corner-sharing OLiFeCo2 tetrahedra. In the eighth O2- site, O2- is bonded to one Li1+, one Fe3+, and two Co+3.67+ atoms to form a mixture of distorted edge and corner-sharing OLiFeCo2 tetrahedra.« less
