Materials Data on Mn3(O2F)2 by Materials Project
Abstract
Mn3(O2F)2 is zeta iron carbide-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are six inequivalent Mn+3.33+ sites. In the first Mn+3.33+ site, Mn+3.33+ is bonded to five O2- and one F1- atom to form a mixture of corner and edge-sharing MnO5F octahedra. The corner-sharing octahedra tilt angles range from 47–53°. There are a spread of Mn–O bond distances ranging from 1.88–2.08 Å. The Mn–F bond length is 2.02 Å. In the second Mn+3.33+ site, Mn+3.33+ is bonded to four O2- and two F1- atoms to form MnO4F2 octahedra that share corners with eight MnO4F2 octahedra and edges with two MnO5F octahedra. The corner-sharing octahedra tilt angles range from 39–60°. There are a spread of Mn–O bond distances ranging from 1.93–1.98 Å. There are one shorter (2.03 Å) and one longer (2.10 Å) Mn–F bond lengths. In the third Mn+3.33+ site, Mn+3.33+ is bonded to four O2- and two F1- atoms to form MnO4F2 octahedra that share corners with eight MnO4F2 octahedra and edges with two MnO5F octahedra. The corner-sharing octahedra tilt angles range from 40–54°. There is two shorter (1.94 Å) and two longer (1.96 Å) Mn–O bond length. There are one shortermore »
