title: Materials Data on Fe2Co3O10 by Materials Project

description: Fe2Co3O10 is trigonal omega-derived structured and crystallizes in the monoclinic Pm space group. The structure is two-dimensional and consists of one Fe2Co3O10 sheet oriented in the (-1, 0, 2) direction. there are four inequivalent Fe sites. In the first Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share edges with two equivalent FeO6 octahedra and edges with four CoO6 octahedra. All Fe–O bond lengths are 1.97 Å. In the second Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share edges with two equivalent CoO6 octahedra and edges with four FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 1.91–1.98 Å. In the third Fe site, Fe is bonded to six O atoms to form edge-sharing FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 1.98–2.05 Å. In the fourth Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share edges with two equivalent CoO6 octahedra and edges with four FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 1.90–1.97 Å. There are six inequivalent Co sites. In the first Co site, Co is bonded to six O atoms to form edge-sharing CoO6 octahedra. There is two shorter (1.89 Å) and four longer (1.91 Å) Co–O bond length. In the second Co site, Co is bonded to six O atoms to form edge-sharing CoO6 octahedra. There are a spread of Co–O bond distances ranging from 1.88–1.91 Å. In the third Co site, Co is bonded to six O atoms to form edge-sharing CoO6 octahedra. There are a spread of Co–O bond distances ranging from 1.89–1.91 Å. In the fourth Co site, Co is bonded to six O atoms to form CoO6 octahedra that share edges with two equivalent FeO6 octahedra and edges with four CoO6 octahedra. There are a spread of Co–O bond distances ranging from 1.87–1.91 Å. In the fifth Co site, Co is bonded to six O atoms to form CoO6 octahedra that share edges with two equivalent CoO6 octahedra and edges with four FeO6 octahedra. There are a spread of Co–O bond distances ranging from 1.85–1.90 Å. In the sixth Co site, Co is bonded to six O atoms to form CoO6 octahedra that share edges with two equivalent FeO6 octahedra and edges with four CoO6 octahedra. There are a spread of Co–O bond distances ranging from 1.88–1.91 Å. There are twenty inequivalent O sites.
