Materials Data on NaLi2MnF6 by Materials Project
(Li)2NaMnF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight lithium molecules and one NaMnF6 framework. In the NaMnF6 framework, Na1+ is bonded to six equivalent F1- atoms to form NaF6 octahedra that share corners with six equivalent MnF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Na–F bond lengths are 2.16 Å. Mn3+ is bonded to six equivalent F1- atoms to form MnF6 octahedra that share corners with six equivalent NaF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Mn–F bond lengths are 1.93 Å. F1- is bonded in a linear geometry to one Na1+ and one Mn3+ atom.
