The material structure described by Ag2VP2O8 crystallizes in the monoclinic P2_1/c space group. V(1) is bonded to one O(3), one O(4), one O(5), one O(6), one O(7), and one O(8) atom to form distorted VO6 octahedra that share corners with two equivalent P(2)O4 tetrahedra and corners with three equivalent P(1)O4 tetrahedra. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(8) atoms. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to one O(1), one O(3), one O(6), and one O(7) atom. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form PO4 tetrahedra that share corners with three equivalent V(1)O6 octahedra and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 40-48°. In the second P site, P(2) is bonded to one O(1), one O(2), one O(6), and one O(7) atom to form PO4 tetrahedra that share corners with two equivalent V(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 42-47°. There are eight inequivalent O sites. In the first O site, O(4) is bonded in a distorted bent 150 degrees geometry to one V(1) and one P(1) atom. In the second O site, O(5) is bonded in a distorted bent 120 degrees geometry to one V(1) and one P(1) atom. In the third O site, O(6) is bonded in a 3-coordinate geometry to one V(1), one Ag(2), and one P(2) atom. In the fourth O site, O(7) is bonded in a 3-coordinate geometry to one V(1), one Ag(2), and one P(2) atom. In the fifth O site, O(8) is bonded in a 3-coordinate geometry to one V(1) and two equivalent Ag(1) atoms. In the sixth O site, O(1) is bonded in a distorted single-bond geometry to one Ag(2), two equivalent Ag(1), and one P(2) atom.
