Materials Data on NaFeH8(NF3)2 by Materials Project
Abstract
(NH4)2NaFeF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight ammonium molecules and one NaFeF6 framework. In the NaFeF6 framework, Na1+ is bonded to six equivalent F1- atoms to form NaF6 octahedra that share corners with six equivalent FeF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Na–F bond lengths are 2.40 Å. Fe3+ is bonded to six equivalent F1- atoms to form FeF6 octahedra that share corners with six equivalent NaF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Fe–F bond lengths are 1.90 Å. F1- is bonded in a linear geometry to one Na1+ and one Fe3+ atom.
