Materials Data on BaMn4O8 by Materials Project
BaMn4O8 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Ba2+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. All Ba–O bond lengths are 2.88 Å. There are two inequivalent Mn+3.50+ sites. In the first Mn+3.50+ site, Mn+3.50+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of Mn–O bond distances ranging from 1.89–2.10 Å. In the second Mn+3.50+ site, Mn+3.50+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of Mn–O bond distances ranging from 1.89–2.10 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to three Mn+3.50+ atoms. In the second O2- site, O2- is bonded in a trigonal planar geometry to three Mn+3.50+ atoms. In the third O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Ba2+ and three equivalent Mn+3.50+ atoms. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Ba2+ and three equivalent Mn+3.50+ atoms.
