The material structure described by Ag2ZnP2O7 crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. In the second Ag site, Ag(2) is bonded in a 2-coordinate geometry to two equivalent O(2) atoms. Zn(1) is bonded to four equivalent O(1) atoms to form ZnO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form PO4 tetrahedra that share  a cornercorner with one P(1)O4 tetrahedra and corners with two equivalent Zn(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(2) is bonded in a 4-coordinate geometry to one Ag(2), two equivalent Ag(1), and one P(1) atom. In the second O site, O(3) is bonded in a distorted bent 150 degrees geometry to two equivalent P(1) atoms. In the third O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Ag(1), one Zn(1), and one P(1) atom. is represented by the CIF file [CIF]
