Materials Data on LiMnF3 by Materials Project

Abstract

LiMnF3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a rectangular see-saw-like geometry to four F1- atoms. There is two shorter (1.89 Å) and two longer (1.90 Å) Li–F bond length. In the second Li1+ site, Li1+ is bonded in a distorted rectangular see-saw-like geometry to four F1- atoms. There are a spread of Li–F bond distances ranging from 2.10–2.24 Å. There are two inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded to six F1- atoms to form a mixture of edge and corner-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles are 63°. There are a spread of Mn–F bond distances ranging from 2.12–2.24 Å. In the second Mn2+ site, Mn2+ is bonded to six F1- atoms to form a mixture of edge and corner-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles are 63°. There are a spread of Mn–F bond distances ranging from 2.12–2.24 Å. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a 3-coordinate geometry to one Li1+ and two equivalent Mn2+ atoms. In the second F1- site, F1- is bonded in a distorted trigonal planar geometry to one Li1+ and two equivalent Mn2+ atoms. In the third F1- site, F1- is bonded to two equivalent Li1+ and two Mn2+ atoms to form a mixture of edge and corner-sharing FLi2Mn2 tetrahedra. In the fourth F1- site, F1- is bonded to two equivalent Li1+ and two Mn2+ atoms to form a mixture of edge and corner-sharing FLi2Mn2 tetrahedra. In the fifth F1- site, F1- is bonded in a distorted trigonal planar geometry to one Li1+ and two equivalent Mn2+ atoms. In the sixth F1- site, F1- is bonded in a 3-coordinate geometry to one Li1+ and two equivalent Mn2+ atoms.
