(NH4)2NaFeF6 is High-temperature superconductor-derived structured and crystallizes in the cubic Fm-3m space group. The structure consists of eight ammonium molecules inside a NaFeF6 framework. In the NaFeF6 framework, Na(1) is bonded to six equivalent F(1) atoms to form NaF6 octahedra that share corners with six equivalent Fe(1)F6 octahedra. The corner-sharing octahedra are not tilted. Fe(1) is bonded to six equivalent F(1) atoms to form FeF6 octahedra that share corners with six equivalent Na(1)F6 octahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a linear geometry to one Na(1) and one Fe(1) atom.
