Materials Data on KCN2 by Materials Project
KCN2 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight equivalent N+2.50- atoms. All K–N bond lengths are 3.03 Å. C4+ is bonded in a linear geometry to two equivalent N+2.50- atoms. Both C–N bond lengths are 1.24 Å. N+2.50- is bonded in a distorted single-bond geometry to four equivalent K1+ and one C4+ atom.
