The material structure described by AgPO3 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(2), and two equivalent O(4) atoms. In the second Ag site, Ag(2) is bonded to one O(4), two equivalent O(1), and two equivalent O(5) atoms to form distorted AgO5 trigonal bipyramids that share corners with two equivalent P(1)O4 tetrahedra, corners with three equivalent P(2)O4 tetrahedra, corners with two equivalent Ag(2)O5 trigonal bipyramids, and  an edgeedge with one Ag(2)O5 trigonal bipyramid. 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(6) atom to form PO4 tetrahedra that share corners with two equivalent P(2)O4 tetrahedra and corners with two equivalent Ag(2)O5 trigonal bipyramids. In the second P site, P(2) is bonded to one O(3), one O(4), one O(5), and one O(6) atom to form PO4 tetrahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with three equivalent Ag(2)O5 trigonal bipyramids. There are six inequivalent O sites. In the first O site, O(5) is bonded in a distorted single-bond geometry to two equivalent Ag(2) and one P(2) atom. In the second O site, O(6) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the third O site, O(1) is bonded in a distorted single-bond geometry to one Ag(1), two equivalent Ag(2), and one P(1) atom. In the fourth O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Ag(1) and one P(1) atom. In the fifth O site, O(3) is bonded in a bent 150 degrees geometry to one P(1) and one P(2) atom. In the sixth O site, O(4) is bonded in a distorted single-bond geometry to one Ag(2), two equivalent Ag(1), and one P(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
