Materials Data on KNO2 by Materials Project
KNO2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. K1+ is bonded in a hexagonal planar geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.81–2.96 Å. N3+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both N–O bond lengths are 1.27 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three equivalent K1+ and one N3+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three equivalent K1+ and one N3+ atom.
