Materials Data on KNO3 by Materials Project
KNO3 is Calcite-like structured and crystallizes in the trigonal R32 space group. The structure is three-dimensional. K1+ is bonded to six equivalent O2- atoms to form distorted corner-sharing KO6 octahedra. The corner-sharing octahedral tilt angles are 67°. All K–O bond lengths are 2.78 Å. N5+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All N–O bond lengths are 1.27 Å. O2- is bonded in a trigonal planar geometry to two equivalent K1+ and one N5+ atom.
