Materials Data on BaH2(S2O3)2 by Materials Project
(BaH(SO3)2)2H2(S)4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four hydrogen molecules, eight hydrogen sulfide molecules, and one BaH(SO3)2 framework. In the BaH(SO3)2 framework, Ba2+ is bonded in a 6-coordinate geometry to one H1+ and six O2- atoms. The Ba–H bond length is 3.06 Å. There are a spread of Ba–O bond distances ranging from 2.68–2.77 Å. H1+ is bonded in a single-bond geometry to one Ba2+ atom. There are two inequivalent S2+ sites. In the first S2+ site, S2+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. All S–O bond lengths are 1.47 Å. In the second S2+ site, S2+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. All S–O bond lengths are 1.47 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ba2+ and one S2+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ba2+ and one S2+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+ and one S2+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+ and one S2+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ba2+ and one S2+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+ and one S2+ atom.
