Title: Materials Data on Fe2CoO4 by Materials Project

Abstract

CoFe2O4 is Spinel structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six equivalent CoO4 tetrahedra and edges with six FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 1.99–2.09 Å. In the second Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six equivalent CoO4 tetrahedra and edges with six FeO6 octahedra. There is two shorter (1.98 Å) and four longer (1.99 Å) Fe–O bond length. In the third Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six equivalent CoO4 tetrahedra and edges with six FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 2.02–2.04 Å. In the fourth Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six equivalent CoO4 tetrahedra and edges with six FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 1.97–1.99 Å. Co2+ is bonded to four O2- atoms tomore » form CoO4 tetrahedra that share corners with twelve FeO6 octahedra. The corner-sharing octahedra tilt angles range from 56–61°. There are a spread of Co–O bond distances ranging from 1.97–1.99 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to three Fe3+ and one Co2+ atom. In the second O2- site, O2- is bonded to three Fe3+ and one Co2+ atom to form a mixture of distorted edge and corner-sharing OFe3Co trigonal pyramids. In the third O2- site, O2- is bonded in a rectangular see-saw-like geometry to three Fe3+ and one Co2+ atom. In the fourth O2- site, O2- is bonded to three Fe3+ and one Co2+ atom to form a mixture of distorted edge and corner-sharing OFe3Co trigonal pyramids.« less
