Materials Data on Ag3PO4 by Materials Project

Ag3PO4 crystallizes in the trigonal R3c space group. The structure is three-dimensional. Ag1+ is bonded in a distorted see-saw-like geometry to four O2- atoms. There are a spread of Ag–O bond distances ranging from 2.34–2.50 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is three shorter (1.57 Å) and one longer (1.58 Å) P–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted tetrahedral geometry to three equivalent Ag1+ and one P5+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three equivalent Ag1+ and one P5+ atom.
