Materials Data on Ag2Se by Materials Project
Ag2Se crystallizes in the orthorhombic P222_1 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 Ag1+ and three equivalent Se2- atoms. There are a spread of Ag–Ag bond distances ranging from 2.70–2.90 Å. There are a spread of Ag–Se bond distances ranging from 2.63–2.92 Å. In the second Ag1+ site, Ag1+ is bonded in a 10-coordinate geometry to four Ag1+ and six equivalent Se2- atoms. Both Ag–Ag bond lengths are 2.80 Å. There are four shorter (3.05 Å) and two longer (3.18 Å) Ag–Se bond lengths. In the third Ag1+ site, Ag1+ is bonded in a 10-coordinate geometry to four Ag1+ and six equivalent Se2- atoms. Both Ag–Ag bond lengths are 2.85 Å. There are a spread of Ag–Se bond distances ranging from 3.03–3.17 Å. Se2- is bonded in a 9-coordinate geometry to nine Ag1+ atoms.
