The structure described by AgInP2O7 crystallizes in the monoclinic P2_1/c space group. Ag(1) is bonded in a 6-coordinate geometry to one O(2), one O(3), one O(4), one O(5), one O(6), and one O(7) atom. In(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form InO6 octahedra that share corners with three equivalent P(1)O4 tetrahedra and corners with three equivalent P(2)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(3), and one O(7) atom to form PO4 tetrahedra that share corners with three equivalent In(1)O6 octahedra and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 22-52°. In the second P site, P(2) is bonded to one O(4), one O(5), one O(6), and one O(7) atom to form PO4 tetrahedra that share corners with three equivalent In(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 35-54°. There are seven inequivalent O sites. In the first O site, O(5) is bonded in a distorted bent 120 degrees geometry to one Ag(1), one In(1), and one P(2) atom. In the second O site, O(6) is bonded in a 3-coordinate geometry to one Ag(1), one In(1), and one P(2) atom. In the third O site, O(7) is bonded in a distorted bent 150 degrees geometry to one Ag(1), one P(1), and one P(2) atom. In the fourth O site, O(1) is bonded in a bent 150 degrees geometry to one In(1) and one P(1) atom. In the fifth O site, O(2) is bonded in a 2-coordinate geometry to one Ag(1), one In(1), and one P(1) atom. In the sixth O site, O(3) is bonded in a distorted trigonal planar geometry to one Ag(1), one In(1), and one P(1) atom. In the seventh O site, O(4) is bonded in a 3-coordinate geometry to one Ag(1), one In(1), and one P(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
