Materials Data on K2Se2N by Materials Project
(KSe)4N2 is alpha boron-derived structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional and consists of four ammonia molecules and one KSe framework. In the KSe framework, K1+ is bonded in a 6-coordinate geometry to six equivalent Se+1.50- atoms. There are a spread of K–Se bond distances ranging from 3.39–3.48 Å. Se+1.50- is bonded in a 7-coordinate geometry to six equivalent K1+ and one Se+1.50- atom. The Se–Se bond length is 2.40 Å.
