Materials Data on KNOF2 by Materials Project
KNOF2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to six equivalent F1- atoms. There are a spread of K–F bond distances ranging from 2.71–2.79 Å. N3+ is bonded in a trigonal non-coplanar geometry to one O2- and two equivalent F1- atoms. The N–O bond length is 1.14 Å. Both N–F bond lengths are 1.93 Å. O2- is bonded in a single-bond geometry to one N3+ atom. F1- is bonded in a 4-coordinate geometry to three equivalent K1+ and one N3+ atom.
