Materials Data on KCNO by Materials Project

Abstract

KCNO crystallizes in the orthorhombic Ima2 space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to four equivalent N3- and four equivalent O2- atoms. There are two shorter (2.97 Å) and two longer (2.98 Å) K–N bond lengths. There are two shorter (2.97 Å) and two longer (3.00 Å) K–O bond lengths. C4+ is bonded in a linear geometry to one N3- and one O2- atom. The C–N bond length is 1.20 Å. The C–O bond length is 1.23 Å. N3- is bonded in a distorted single-bond geometry to four equivalent K1+ and one C4+ atom. O2- is bonded in a distorted single-bond geometry to four equivalent K1+ and one C4+ atom.
