Materials Data on NaPH6 by Materials Project
NaPH6 is alpha Rhenium trioxide-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Na1+ is bonded to six equivalent H+0.33+ atoms to form NaH6 octahedra that share corners with six equivalent PH6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Na–H bond lengths are 2.23 Å. P3- is bonded to six equivalent H+0.33+ atoms to form PH6 octahedra that share corners with six equivalent NaH6 octahedra. The corner-sharing octahedral tilt angles are 0°. All P–H bond lengths are 1.49 Å. H+0.33+ is bonded in a linear geometry to one Na1+ and one P3- atom.
