The structure described by Ag3Tl2(PO4)3 crystallizes in the monoclinic C2/c space group. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. In the second Ag site, Ag(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted AgO6 octahedra that share corners with two equivalent Tl(1)O6 octahedra, corners with two equivalent P(1)O4 tetrahedra, corners with four equivalent P(2)O4 tetrahedra, and edges with two equivalent Ag(2)O6 octahedra. The corner-sharing octahedral tilt angles are 73°. In the third Ag site, Ag(3) is bonded in a distorted square co-planar geometry to four equivalent O(5) atoms. Tl(1) is bonded to one O(1), one O(3), one O(4), one O(5), and two equivalent O(6) atoms to form TlO6 octahedra that share  a cornercorner with one Ag(2)O6 octahedra, corners with two equivalent P(1)O4 tetrahedra, corners with four equivalent P(2)O4 tetrahedra, and  an edgeedge with one Tl(1)O6 octahedra. The corner-sharing octahedral tilt angles are 73°. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form PO4 tetrahedra that share corners with two equivalent Ag(2)O6 octahedra and corners with four equivalent Tl(1)O6 octahedra.

In the first O site, O(1) is bonded in a 3-coordinate geometry to one Ag(2), one Tl(1), and one P(1) atom. In the second O site, O(2) is bonded in a 1-coordinate geometry to one Ag(1), two equivalent Ag(2), and one P(2) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Ag(1), one Tl(1), and one P(1) atom.
