Materials Data on KSnN3 by Materials Project
KSnN3 crystallizes in the trigonal P-3 space group. The structure is two-dimensional and consists of one KSnN3 sheet oriented in the (0, 0, 1) direction. K1+ is bonded in a 6-coordinate geometry to six equivalent N+1.67- atoms. There are three shorter (2.81 Å) and three longer (3.15 Å) K–N bond lengths. Sn4+ is bonded in a distorted T-shaped geometry to three equivalent N+1.67- atoms. All Sn–N bond lengths are 2.15 Å. N+1.67- is bonded in a 3-coordinate geometry to two equivalent K1+ and one Sn4+ atom.
