Materials Data on Li3FeF6 by Materials Project
Abstract
Li3FeF6 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are five inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four F1- atoms to form LiF4 tetrahedra that share a cornercorner with one LiF6 octahedra, corners with four FeF6 octahedra, and an edgeedge with one LiF4 tetrahedra. The corner-sharing octahedra tilt angles range from 51–64°. There are a spread of Li–F bond distances ranging from 1.88–1.92 Å. In the second Li1+ site, Li1+ is bonded in a 6-coordinate geometry to six F1- atoms. There are a spread of Li–F bond distances ranging from 1.93–2.48 Å. In the third Li1+ site, Li1+ is bonded in a 6-coordinate geometry to six F1- atoms. There are a spread of Li–F bond distances ranging from 1.94–2.54 Å. In the fourth Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five F1- atoms. There are a spread of Li–F bond distances ranging from 1.89–2.23 Å. In the fifth Li1+ site, Li1+ is bonded to six F1- atoms to form LiF6 octahedra that share corners with two equivalent FeF6 octahedra, corners with two equivalent LiF4 tetrahedra, and edges with two equivalent FeF6 octahedra.

In the third F1- site, F1- is bonded in a 4-coordinate geometry to three Li1+ and one Fe3+ atom. In the fourth F1- site, F1- is bonded in a distorted rectangular see-saw-like geometry to three Li1+ and one Fe3+ atom.

In the sixth F1- site, F1- is bonded in a distorted trigonal planar geometry to two Li1+ and one Fe3+ atom. In the seventh F1- site, F1- is bonded in a 4-coordinate geometry to three Li1+ and one Fe3+ atom. In the eighth F1- site, F1- is bonded to three Li1+ and one Fe3+ atom to form a mixture of distorted edge and corner-sharing FLi3Fe trigonal pyramids.
