Materials Data on Li2CN2 by Materials Project
Li2CN2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Li1+ is bonded to four equivalent N3- atoms to form a mixture of distorted edge and corner-sharing LiN4 tetrahedra. All Li–N bond lengths are 2.09 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 5-coordinate geometry to four equivalent Li1+ and one C4+ atom.
