The crystal structure described by Ag9(PbO3)4 crystallizes in the monoclinic P2_1/c space group. There are five inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a linear geometry to one O(1) and one O(4) atom. In the second Ag site, Ag(2) is bonded in a linear geometry to two equivalent O(5) atoms. In the third Ag site, Ag(3) is bonded in a trigonal non-coplanar geometry to one O(4), one O(5), and one O(6) atom. In the fourth Ag site, Ag(4) is bonded in a linear geometry to one O(2) and one O(3) atom. In the fifth Ag site, Ag(5) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded to one O(1), one O(4), one O(5), one O(6), and two equivalent O(3) atoms to form edge-sharing PbO6 octahedra. In the second Pb site, Pb(2) is bonded to one O(1), one O(4), one O(5), one O(6), and two equivalent O(2) atoms to form edge-sharing PbO6 octahedra. There are six inequivalent O sites. In the first O site, O(5) is bonded to one Ag(2), one Ag(3), one Pb(1), and one Pb(2) atom to form corner-sharing OAg2Pb2 tetrahedra. In the second O site, O(6) is bonded in a trigonal non-coplanar geometry to one Ag(3), one Pb(1), and one Pb(2) atom. In the third O site, O(1) is bonded to one Ag(1), one Ag(5), one Pb(1), and one Pb(2) atom to form a mixture of edge and corner-sharing OAg2Pb2 tetrahedra. In the fourth O site, O(2) is bonded to one Ag(4), one Ag(5), and two equivalent Pb(2) atoms to form a mixture of edge and corner-sharing OAg2Pb2 tetrahedra. In the fifth O site, O(3) is bonded to one Ag(4), one Ag(5), and two equivalent Pb(1) atoms to form a mixture of edge and corner-sharing OAg2Pb2 tetrahedra. In the sixth O site, O(4) is bonded to one Ag(1), one Ag(3), one Pb(1), and one Pb(2) atom to form a mixture of edge and corner-sharing OAg2Pb2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
