Materials Data on KCSeN by Materials Project
KSeCN crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. K1+ is bonded in a 2-coordinate geometry to three equivalent N3- and three equivalent Se2- atoms. There are a spread of K–N bond distances ranging from 2.85–3.10 Å. There are a spread of K–Se bond distances ranging from 3.48–3.55 Å. C4+ is bonded in a distorted single-bond geometry to one N3- and one Se2- atom. The C–N bond length is 1.19 Å. The C–Se bond length is 1.80 Å. N3- is bonded in a 1-coordinate geometry to three equivalent K1+ and one C4+ atom. Se2- is bonded to three equivalent K1+ and one C4+ atom to form distorted corner-sharing SeK3C trigonal pyramids.
