Materials Data on Ag5GeO4 by Materials Project
Ag5GeO4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are five inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Ag–O bond distances ranging from 2.29–2.78 Å. In the second Ag1+ site, Ag1+ is bonded in a 3-coordinate geometry to three O2- atoms. There are one shorter (2.25 Å) and two longer (2.42 Å) Ag–O bond lengths. In the third Ag1+ site, Ag1+ is bonded in an L-shaped geometry to two O2- atoms. There are one shorter (2.35 Å) and one longer (2.44 Å) Ag–O bond lengths. In the fourth Ag1+ site, Ag1+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Ag–O bond distances ranging from 2.35–2.61 Å. In the fifth Ag1+ site, Ag1+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Ag–O bond distances ranging from 2.34–2.50 Å. Ge3+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Ge–O bond distances ranging from 1.78–1.80 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three Ag1+ and one Ge3+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to four Ag1+ and one Ge3+ atom. In the third O2- site, O2- is bonded in a 5-coordinate geometry to four Ag1+ and one Ge3+ atom. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to four Ag1+ and one Ge3+ atom.
