Title: Materials Data on Mn2Co5O12 by Materials Project

Abstract

Mn2Co5O12 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are two inequivalent Mn7+ sites. In the first Mn7+ site, Mn7+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with two equivalent CoO6 octahedra and edges with five CoO6 octahedra. The corner-sharing octahedral tilt angles are 19°. There is two shorter (1.89 Å) and four longer (1.94 Å) Mn–O bond length. In the second Mn7+ site, Mn7+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with two equivalent CoO6 octahedra and edges with eight CoO6 octahedra. The corner-sharing octahedral tilt angles are 16°. There are a spread of Mn–O bond distances ranging from 1.89–2.00 Å. There are four inequivalent Co2+ sites. In the first Co2+ site, Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent CoO6 octahedra, edges with three equivalent MnO6 octahedra, and edges with five CoO6 octahedra. The corner-sharing octahedral tilt angles are 16°. There are a spread of Co–O bond distances ranging from 1.89–2.00 Å. In the second Co2+ site, Co2+ is bonded to six O2- atoms to form distorted CoO6 octahedra that share corners withmore » two MnO6 octahedra, corners with three CoO6 octahedra, edges with two MnO6 octahedra, and edges with three CoO6 octahedra. The corner-sharing octahedra tilt angles range from 10–19°. There are a spread of Co–O bond distances ranging from 1.81–2.38 Å. In the third Co2+ site, Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent CoO6 octahedra, edges with three equivalent MnO6 octahedra, and edges with five CoO6 octahedra. The corner-sharing octahedral tilt angles are 10°. There is four shorter (1.90 Å) and two longer (1.96 Å) Co–O bond length. In the fourth Co2+ site, Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent CoO6 octahedra, edges with two equivalent CoO6 octahedra, and edges with three equivalent MnO6 octahedra. The corner-sharing octahedral tilt angles are 13°. There are a spread of Co–O bond distances ranging from 1.81–1.95 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted T-shaped geometry to one Mn7+ and two Co2+ atoms. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Mn7+ and three Co2+ atoms. In the third O2- site, O2- is bonded in a T-shaped geometry to one Mn7+ and two Co2+ atoms. In the fourth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Mn7+ and three Co2+ atoms. In the fifth O2- site, O2- is bonded in a T-shaped geometry to one Mn7+ and two Co2+ atoms. In the sixth O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Mn7+ and three Co2+ atoms.« less
