Title: Materials Data on Mn(CoO2)4 by Materials Project

Abstract

Mn(CoO2)4 is beta indium sulfide-derived structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Mn7+ is bonded to six O2- atoms to form MnO6 octahedra that share edges with eight CoO6 octahedra. There are a spread of Mn–O bond distances ranging from 1.92–1.94 Å. There are four inequivalent Co+2.25+ sites. In the first Co+2.25+ site, Co+2.25+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six equivalent CoO6 octahedra, edges with two equivalent MnO6 octahedra, and edges with four CoO6 octahedra. The corner-sharing octahedra tilt angles range from 10–14°. There are a spread of Co–O bond distances ranging from 2.04–2.16 Å. In the second Co+2.25+ site, Co+2.25+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six equivalent CoO6 octahedra, edges with two equivalent MnO6 octahedra, and edges with four CoO6 octahedra. The corner-sharing octahedra tilt angles range from 10–14°. There are two shorter (2.02 Å) and four longer (2.05 Å) Co–O bond lengths. In the third Co+2.25+ site, Co+2.25+ is bonded to six O2- atoms to form CoO6 octahedra that share edges with two equivalent MnO6 octahedra and edges with six CoO6 octahedra. There aremore » a spread of Co–O bond distances ranging from 1.88–1.91 Å. In the fourth Co+2.25+ site, Co+2.25+ is bonded to six O2- atoms to form CoO6 octahedra that share edges with two equivalent MnO6 octahedra and edges with six CoO6 octahedra. There is two shorter (1.91 Å) and four longer (1.92 Å) Co–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted T-shaped geometry to one Mn7+ and two Co+2.25+ atoms. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Mn7+ and three Co+2.25+ atoms. In the third O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Mn7+ and three Co+2.25+ atoms. In the fourth O2- site, O2- is bonded in a rectangular see-saw-like geometry to four Co+2.25+ atoms.« less
