Materials Data on Ag2S by Materials Project

Ag2S crystallizes in the monoclinic Pc space group. The structure is three-dimensional. there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a trigonal planar geometry to three equivalent S2- atoms. There are a spread of Ag–S bond distances ranging from 2.54–2.60 Å. In the second Ag1+ site, Ag1+ is bonded in a distorted trigonal planar geometry to three equivalent S2- atoms. There are a spread of Ag–S bond distances ranging from 2.54–2.64 Å. S2- is bonded in a 6-coordinate geometry to six Ag1+ atoms.
