Materials Data on K8NO3 by Materials Project

K8NO3 is Fluorite-derived structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. K1+ is bonded to one N2- and three equivalent O2- atoms to form a mixture of edge and corner-sharing KNO3 tetrahedra. The K–N bond length is 2.88 Å. All K–O bond lengths are 2.83 Å. N2- is bonded in a body-centered cubic geometry to eight equivalent K1+ atoms. O2- is bonded in a body-centered cubic geometry to eight equivalent K1+ atoms.
