The compound described by NaHF2 crystallizes in the trigonal R-3m space group. Na(1) is bonded to six equivalent F(1) atoms to form edge-sharing NaF6 octahedra. H(1) is bonded in a linear geometry to two equivalent F(1) atoms. F(1) is bonded in a 4-coordinate geometry to three equivalent Na(1) and one H(1) atom. is represented by the CIF file [CIF]
