Ag3(PO4)2 crystallizes in the trigonal R3 space group. Ag(1) is bonded in a distorted square co-planar geometry to one O(3), one O(4), and two equivalent O(2) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a tetrahedral geometry to one O(1) and three equivalent O(2) atoms. In the second P site, P(2) is bonded in a tetrahedral geometry to one O(4) and three equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one P(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Ag(1) and one P(1) atom. In the third O site, O(3) is bonded in a distorted water-like geometry to one Ag(1) and one P(2) atom. In the fourth O site, O(4) is bonded in a tetrahedral geometry to three equivalent Ag(1) and one P(2) atom.
