Materials Data on Ag2O by Materials Project

Abstract

Ag2O crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are six inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a distorted bent 150 degrees geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.17 Å. In the second Ag1+ site, Ag1+ is bonded in a linear geometry to two O2- atoms. There are one shorter (2.09 Å) and one longer (2.12 Å) Ag–O bond lengths. In the third Ag1+ site, Ag1+ is bonded in a linear geometry to two O2- atoms. There are one shorter (2.08 Å) and one longer (2.09 Å) Ag–O bond lengths. In the fourth Ag1+ site, Ag1+ is bonded in a single-bond geometry to one O2- atom. The Ag–O bond length is 2.19 Å. In the fifth Ag1+ site, Ag1+ is bonded in a distorted bent 150 degrees geometry to three O2- atoms. There are two shorter (2.20 Å) and one longer (2.95 Å) Ag–O bond lengths. In the sixth Ag1+ site, Ag1+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are two shorter (2.17 Å) and one longer (2.50 Å) Ag–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to five Ag1+ atoms. In the second O2- site, O2- is bonded in a distorted see-saw-like geometry to four Ag1+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to four Ag1+ atoms.
