Materials Data on Ag2SeO3 by Materials Project

Abstract

Ag2SeO3 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 6-coordinate geometry to six O2- atoms. There are a spread of Ag–O bond distances ranging from 2.39–3.06 Å. In the second Ag1+ site, Ag1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Ag–O bond distances ranging from 2.33–2.80 Å. Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.74 Å) and one longer (1.75 Å) Se–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to four Ag1+ and one Se4+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to four Ag1+ and one Se4+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three Ag1+ and one Se4+ atom.
