Materials Data on Na2CN2 by Materials Project
Na2CN2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Na1+ is bonded to five equivalent N3- atoms to form a mixture of distorted edge and corner-sharing NaN5 square pyramids. There are a spread of Na–N bond distances ranging from 2.43–2.62 Å. C4+ is bonded in a linear geometry to two equivalent N3- atoms. Both C–N bond lengths are 1.24 Å. N3- is bonded in a 1-coordinate geometry to five equivalent Na1+ and one C4+ atom.
