Materials Data on K2HS2NO6 by Materials Project

(KSO3)2NH crystallizes in the monoclinic Cc space group. The structure is three-dimensional and consists of four ammonia molecules and one KSO3 framework. In the KSO3 framework, there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.75–3.36 Å. In the second K1+ site, K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.77–3.30 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 is one shorter (1.46 Å) and two longer (1.47 Å) S–O bond length. In the second S2+ site, S2+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.46 Å) and two longer (1.47 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 single-bond geometry to three K1+ and one S2+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S2+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S2+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three 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.

(KSO3)2NH crystallizes in the monoclinic C2/c space group. The structure is three-dimensional and consists of four ammonia molecules and one KSO3 framework. In the KSO3 framework, K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.76–3.32 Å. S2+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.46 Å) and two longer (1.47 Å) S–O bond length. There are three 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 three equivalent K1+ and one S2+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to three equivalent K1+ and one S2+ atom.

Materials Data on K2HS2NO6 by Materials Project

(KSO3)2NH is alpha carbon monoxide-like structured and crystallizes in the monoclinic Pc space group. The structure is zero-dimensional and consists of two ammonia molecules and two KSO3 clusters. In each KSO3 cluster, there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 2-coordinate geometry to two O2- atoms. There are one shorter (2.73 Å) and one longer (2.85 Å) K–O bond lengths. In the second K1+ site, K1+ is bonded in a 2-coordinate geometry to two O2- atoms. There are one shorter (2.77 Å) and one longer (2.79 Å) K–O bond lengths. 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 1.45–1.48 Å. In the second 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 1.45–1.48 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one S2+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one S2+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one S2+ atom.
