Materials Data on Ag2SO3 by Materials Project

Abstract

Ag2SO3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a distorted see-saw-like geometry to four O2- atoms. There are a spread of Ag–O bond distances ranging from 2.32–2.57 Å. In the second Ag1+ site, Ag1+ is bonded in a 5-coordinate geometry to one S4+ and four O2- atoms. The Ag–S bond length is 2.51 Å. There are a spread of Ag–O bond distances ranging from 2.45–2.88 Å. S4+ is bonded in a trigonal non-coplanar geometry to one Ag1+ and three O2- atoms. There are a spread of S–O bond distances ranging from 1.52–1.54 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three Ag1+ and one S4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Ag1+ and one S4+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to three Ag1+ and one S4+ atom.
