Materials Data on NaPF6 by Materials Project

NaPF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Na1+ is bonded to six equivalent F1- atoms to form NaF6 octahedra that share corners with six equivalent PF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Na–F bond lengths are 2.31 Å. P5+ is bonded to six equivalent F1- atoms to form PF6 octahedra that share corners with six equivalent NaF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All P–F bond lengths are 1.64 Å. F1- is bonded in a linear geometry to one Na1+ and one P5+ atom.

Materials Data on NaPF3 by Materials Project

NaPF3 crystallizes in the triclinic P1 space group. The structure is two-dimensional and consists of one NaPF3 sheet oriented in the (-1, 1, 1) direction. Na is bonded in a distorted T-shaped geometry to three F atoms. There are two shorter (2.18 Å) and one longer (2.32 Å) Na–F bond lengths. P is bonded in a distorted T-shaped geometry to three F atoms. There is one shorter (1.66 Å) and two longer (1.80 Å) P–F bond length. There are three inequivalent F sites. In the first F site, F is bonded in a linear geometry to one Na and one P atom. In the second F site, F is bonded in a linear geometry to one Na and one P atom. In the third F site, F is bonded in a bent 150 degrees geometry to one Na and one P atom.
