Materials Data on Sb2S2O9 by Materials Project
Sb2S2O9 crystallizes in the tetragonal P4_12_12 space group. The structure is three-dimensional. Sb3+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Sb–O bond distances ranging from 1.95–2.58 Å. S6+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.48 Å) and two longer (1.51 Å) S–O bond length. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Sb3+ and one S6+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb3+ and one S6+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb3+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Sb3+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Sb3+ atoms.
