The material structure described by NaAlF6(NH4)2 crystallizes in the cubic Fm-3m space group. The structure consists of eight ammonium molecules inside a NaAlF6 framework. In the NaAlF6 framework, Na(1) is bonded to six equivalent F(1) atoms to form NaF6 octahedra that share corners with six equivalent Al(1)F6 octahedra. The corner-sharing octahedra are not tilted. Al(1) is bonded to six equivalent F(1) atoms to form AlF6 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 Al(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
