Materials Data on MnF3 by Materials Project
MnF3 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. Mn3+ is bonded to six F1- atoms to form corner-sharing MnF6 octahedra. The corner-sharing octahedra tilt angles range from 0–21°. There are a spread of Mn–F bond distances ranging from 1.85–2.10 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a linear geometry to two equivalent Mn3+ atoms. In the second F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent Mn3+ atoms.
