Materials Data on Li2Mn2F7 by Materials Project
Abstract
Li2Mn2F7 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four F1- atoms to form LiF4 tetrahedra that share corners with six MnF6 octahedra and corners with two equivalent LiF4 trigonal pyramids. The corner-sharing octahedra tilt angles range from 48–60°. There are a spread of Li–F bond distances ranging from 1.88–1.99 Å. In the second Li1+ site, Li1+ is bonded to four F1- atoms to form distorted LiF4 trigonal pyramids that share corners with five MnF6 octahedra and corners with two equivalent LiF4 tetrahedra. The corner-sharing octahedra tilt angles range from 44–58°. There are a spread of Li–F bond distances ranging from 1.82–2.03 Å. There are two inequivalent Mn+2.50+ sites. In the first Mn+2.50+ site, Mn+2.50+ is bonded to six F1- atoms to form MnF6 octahedra that share a cornercorner with one MnF6 octahedra, corners with four equivalent LiF4 tetrahedra, corners with three equivalent LiF4 trigonal pyramids, and edges with two equivalent MnF6 octahedra. The corner-sharing octahedral tilt angles are 17°. There are a spread of Mn–F bond distances ranging from 1.92–2.17 Å. In the second Mn+2.50+ site, Mn+2.50+ is bonded to sixmore »
