Materials Data on Li2MnF4 by Materials Project
Abstract
Li2MnF4 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six F1- atoms to form LiF6 octahedra that share corners with six equivalent MnF4 tetrahedra and edges with six LiF6 octahedra. There are four shorter (2.06 Å) and two longer (2.07 Å) Li–F bond lengths. In the second Li1+ site, Li1+ is bonded to six F1- atoms to form LiF6 octahedra that share corners with two equivalent LiF6 octahedra, corners with four equivalent MnF4 tetrahedra, and edges with seven LiF6 octahedra. The corner-sharing octahedral tilt angles are 6°. There are a spread of Li–F bond distances ranging from 2.06–2.12 Å. In the third Li1+ site, Li1+ is bonded to six F1- atoms to form LiF6 octahedra that share corners with six equivalent MnF4 tetrahedra and edges with six LiF6 octahedra. There are a spread of Li–F bond distances ranging from 2.01–2.14 Å. Mn2+ is bonded to four F1- atoms to form MnF4 tetrahedra that share corners with ten LiF6 octahedra and a cornercorner with one MnF4 tetrahedra. The corner-sharing octahedra tilt angles range from 54–62°. There are a spread of Mn–F bond distancesmore »
