Abstract

(KSO3)2NH crystallizes in the monoclinic Pc space group. The structure is two-dimensional and consists of two ammonia molecules and one KSO3 sheet oriented in the (0, 0, 1) direction. In the KSO3 sheet, there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.69–3.19 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.66–3.08 Å. There are two inequivalent S2+ sites. In the first S2+ site, S2+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of S–O bond distances ranging from 1.46–1.48 Å. In the second S2+ site, S2+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.46 Å) and one longer (1.48 Å) S–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S2+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one K1+ and one S2+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one S2+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one S2+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+ and one S2+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S2+ atom.
