Materials Data on K2SN2O5 by Materials Project
K2N2SO5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.88–3.19 Å. There are two inequivalent N5+ sites. In the first N5+ site, N5+ is bonded in a single-bond geometry to one O2- atom. The N–O bond length is 1.30 Å. In the second N5+ site, N5+ is bonded in a distorted bent 120 degrees geometry to one S2- and one O2- atom. The N–S bond length is 1.80 Å. The N–O bond length is 1.31 Å. S2- is bonded in a distorted tetrahedral geometry to one N5+ and three O2- atoms. All S–O bond lengths are 1.46 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent K1+ and one S2- atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to four equivalent K1+ and one N5+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to four equivalent K1+ and one S2- atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to four equivalent K1+ and one N5+ atom.
