Materials Data on Mn3O5F by Materials Project

Abstract

Mn3O5F is Hydrophilite-derived structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are four inequivalent Mn+3.67+ sites. In the first Mn+3.67+ site, Mn+3.67+ is bonded to five O2- and one F1- atom to form a mixture of edge and corner-sharing MnO5F octahedra. The corner-sharing octahedra tilt angles range from 44–52°. There are a spread of Mn–O bond distances ranging from 1.89–1.95 Å. The Mn–F bond length is 2.03 Å. In the second Mn+3.67+ site, Mn+3.67+ is bonded to four O2- and two equivalent F1- atoms to form a mixture of edge and corner-sharing MnO4F2 octahedra. The corner-sharing octahedra tilt angles range from 51–52°. There is two shorter (1.94 Å) and two longer (1.96 Å) Mn–O bond length. Both Mn–F bond lengths are 2.11 Å. In the third Mn+3.67+ site, Mn+3.67+ is bonded to five O2- and one F1- atom to form a mixture of edge and corner-sharing MnO5F octahedra. The corner-sharing octahedra tilt angles range from 44–52°. There is one shorter (1.88 Å) and four longer (1.94 Å) Mn–O bond length. The Mn–F bond length is 2.04 Å. In the fourth Mn+3.67+ site, Mn+3.67+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing MnO6 octahedra. The corner-sharing octahedra tilt angles range from 47–52°. There is four shorter (1.94 Å) and two longer (2.00 Å) Mn–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to three Mn+3.67+ atoms. In the second O2- site, O2- is bonded in a trigonal planar geometry to three Mn+3.67+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to three Mn+3.67+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to three Mn+3.67+ atoms. F1- is bonded in a 3-coordinate geometry to three Mn+3.67+ atoms.
