The structure described by NaCrF6 crystallizes in the trigonal R-3 space group. Na(1) is bonded to six equivalent F(1) atoms to form NaF6 octahedra that share corners with six equivalent Cr(1)F6 octahedra. The corner-sharing octahedral tilt angles are 36°. Cr(1) is bonded to six equivalent F(1) atoms to form CrF6 octahedra that share corners with six equivalent Na(1)F6 octahedra. The corner-sharing octahedral tilt angles are 36°. F(1) is bonded in a bent 150 degrees geometry to one Na(1) and one Cr(1) atom. is represented by the CIF file [CIF]
