The crystal structure described by Ag2PbP2O7 crystallizes in the triclinic P-1 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(5) atom. In the second Ag site, Ag(2) is bonded in a 5-coordinate geometry to one O(4), one O(5), one O(6), and two equivalent O(2) atoms. Pb(1) is bonded in a 4-coordinate geometry to one O(3), one O(4), and two equivalent O(7) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 4-coordinate geometry to one O(2), one O(4), one O(5), and one O(6) atom. In the second P site, P(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 seven inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one P(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to two equivalent Ag(2) and one P(1) atom. In the third O site, O(3) is bonded in a distorted water-like geometry to one Ag(1), one Pb(1), and one P(2) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Ag(2), one Pb(1), and one P(1) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one Ag(1), one Ag(2), and one P(1) atom. In the sixth O site, O(6) is bonded in a distorted bent 150 degrees geometry to one Ag(2), one P(1), and one P(2) atom. In the seventh O site, O(7) is bonded in a distorted bent 120 degrees geometry to two equivalent Pb(1) and one P(2) atom. is represented by the CIF card [CIF]
