Title: Materials Data on K5NO4 by Materials Project

Abstract

K5NO4 crystallizes in the triclinic P1 space group. The structure is two-dimensional and consists of one K5NO4 sheet oriented in the (0, 0, 1) direction. there are five inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a single-bond geometry to one O2- atom. The K–O bond length is 2.50 Å. In the second K1+ site, K1+ is bonded in a distorted trigonal planar geometry to three O2- atoms. There are two shorter (2.65 Å) and one longer (2.66 Å) K–O bond lengths. In the third K1+ site, K1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of K–O bond distances ranging from 2.70–3.06 Å. In the fourth K1+ site, K1+ is bonded to four O2- atoms to form distorted corner-sharing KO4 tetrahedra. There are a spread of K–O bond distances ranging from 2.59–2.85 Å. In the fifth K1+ site, K1+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of K–O bond distances ranging from 2.62–2.96 Å. N3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.34–1.36 Å. There are four inequivalentmore » O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three K1+ and one N3+ atom. In the second O2- site, O2- is bonded to three K1+ and one N3+ atom to form distorted OK3N trigonal pyramids that share a cornercorner with one OK5 trigonal bipyramid and corners with two equivalent OK3N trigonal pyramids. In the third O2- site, O2- is bonded in a 5-coordinate geometry to four K1+ and one N3+ atom. In the fourth O2- site, O2- is bonded to five K1+ atoms to form distorted OK5 trigonal bipyramids that share corners with two equivalent OK5 trigonal bipyramids and a cornercorner with one OK3N trigonal pyramid.« less
