Materials Data on BaTeS4O9 by Materials Project
(BaTe(SO3)2)2(S)4(O2)3 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of six hydrogen peroxide molecules; eight hydrogen sulfide molecules; and two BaTe(SO3)2 ribbons oriented in the (0, 1, 0) direction. In each BaTe(SO3)2 ribbon, Ba2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ba–O bond distances ranging from 2.62–3.20 Å. Te4+ is bonded in a distorted single-bond geometry to one O2- atom. The Te–O bond length is 2.87 Å. There are two inequivalent S3+ sites. In the first S3+ site, S3+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. All S–O bond lengths are 1.47 Å. In the second S3+ site, S3+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of S–O bond distances ranging from 1.46–1.49 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+ and one S3+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Te4+ and one S3+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+ and one S3+ atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one Ba2+ and one S3+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ba2+ and one S3+ atom. In the sixth O2- site, O2- is bonded in a distorted linear geometry to one Ba2+ and one S3+ atom.
