The crystal structure described by Ag3PO4 crystallizes in the trigonal R3c space group. Ag(1) is bonded in a distorted see-saw-like geometry to one O(1) and three equivalent O(2) atoms. P(1) is bonded in a tetrahedral geometry to one O(1) and three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a tetrahedral geometry to three equivalent Ag(1) and one P(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to three equivalent Ag(1) and one P(1) atom. is represented by the CIF file [CIF]
