Materials Data on Ag3AsS3 by Materials Project

Abstract

Ag3AsS3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 3-coordinate geometry to four S2- atoms. There are a spread of Ag–S bond distances ranging from 2.48–3.48 Å. In the second Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to four S2- atoms. There are a spread of Ag–S bond distances ranging from 2.53–3.19 Å. In the third Ag1+ site, Ag1+ is bonded in a 3-coordinate geometry to four S2- atoms. There are a spread of Ag–S bond distances ranging from 2.51–3.09 Å. As3+ is bonded in a trigonal non-coplanar geometry to three S2- atoms. There are two shorter (2.29 Å) and one longer (2.34 Å) As–S bond lengths. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a 4-coordinate geometry to four Ag1+ and one As3+ atom. In the second S2- site, S2- is bonded in a 6-coordinate geometry to five Ag1+ and one As3+ atom. In the third S2- site, S2- is bonded in a distorted tetrahedral geometry to three Ag1+ and one As3+ atom.
