Materials Data on NaNiN by Materials Project
NaNiN crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Na1+ is bonded in a 2-coordinate geometry to four equivalent N3- atoms. There are a spread of Na–N bond distances ranging from 2.47–2.87 Å. Ni2+ is bonded in a 3-coordinate geometry to three equivalent N3- atoms. There is two shorter (1.79 Å) and one longer (2.06 Å) Ni–N bond length. N3- is bonded in a 7-coordinate geometry to four equivalent Na1+ and three equivalent Ni2+ atoms.
