Materials Data on K2S2O3 by Materials Project
K2S2O3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of eight hydrogen sulfide molecules and one K2SO3 framework. In the K2SO3 framework, there are four inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of K–O bond distances ranging from 2.72–2.87 Å. In the second K1+ site, K1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of K–O bond distances ranging from 2.74–3.03 Å. In the third K1+ site, K1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of K–O bond distances ranging from 2.72–3.21 Å. In the fourth K1+ site, K1+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of K–O bond distances ranging from 2.68–2.81 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 two shorter (1.49 Å) and one longer (1.50 Å) S–O bond length. In the second S2+ site, S2+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. All S–O bond lengths are 1.49 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to three K1+ and one S2+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three K1+ and one S2+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two K1+ and one S2+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate 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 1-coordinate geometry to two K1+ and one S2+ atom.
