Materials Data on KNO2 by Materials Project

KNO2 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. There are a spread of K–O bond distances ranging from 2.82–2.92 Å. N3+ is bonded in a bent 120 degrees geometry to two equivalent O2- atoms. Both N–O bond lengths are 1.28 Å. O2- is bonded to three equivalent K1+ and one N3+ atom to form a mixture of distorted edge and corner-sharing OK3N tetrahedra.
