There are a spread of K–N bond distances ranging from 2.89–3.46 Å. In the second K1+ site, K1+ is bonded in a 7-coordinate geometry to seven N3- atoms. There are a spread of K–N bond distances ranging from 2.90–3.30 Å. In the third K1+ site, K1+ is bonded in an octahedral geometry to six N3- atoms. There are a spread of K–N bond distances ranging from 2.83–3.09 Å. In the fourth K1+ site, K1+ is bonded in a 7-coordinate geometry to seven N3- atoms.
