Materials Data on K2(SO2)3 by Materials Project
(KSO3)2S crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional and consists of four hydrogen sulfide 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 2.86–3.26 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 2.73–3.08 Å. There are two inequivalent S+3.33+ sites. In the first S+3.33+ site, S+3.33+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.47 Å) and one longer (1.48 Å) S–O bond length. In the second S+3.33+ site, S+3.33+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. All S–O bond lengths are 1.47 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S+3.33+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S+3.33+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S+3.33+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S+3.33+ atom.
