Materials Data on Ag3(AsO4)2 by Materials Project
Ag3(AsO4)2 crystallizes in the trigonal R3 space group. The structure is three-dimensional. Ag2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Ag–O bond distances ranging from 2.17–2.25 Å. There are two inequivalent As5+ sites. In the first As5+ site, As5+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.66 Å) and three longer (1.77 Å) As–O bond length. In the second As5+ site, As5+ is bonded in a tetrahedral geometry to four O2- atoms. There is three shorter (1.71 Å) and one longer (1.85 Å) As–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ag2+ and one As5+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one As5+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Ag2+ and one As5+ atom. In the fourth O2- site, O2- is bonded in a tetrahedral geometry to three equivalent Ag2+ and one As5+ atom.
