The crystal structure described by Bi12PbO19 is Antimony trioxide-derived structured and crystallizes in the trigonal R3 space group. Pb(1) is bonded in a distorted T-shaped geometry to three equivalent O(5) atoms. There are four inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a rectangular see-saw-like geometry to one O(2), one O(3), one O(4), and one O(7) atom. In the second Bi site, Bi(2) is bonded to one O(1), one O(2), one O(4), one O(5), and one O(6) atom to form a mixture of distorted corner and edge-sharing BiO5 square pyramids. In the third Bi site, Bi(3) is bonded to one O(2), one O(5), one O(7), and two equivalent O(6) atoms to form a mixture of distorted corner and edge-sharing BiO5 square pyramids. In the fourth Bi site, Bi(4) is bonded in a 5-coordinate geometry to one O(4), one O(5), one O(7), and two equivalent O(3) atoms. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to three equivalent Bi(2) atoms. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to one Bi(1), one Bi(2), and one Bi(3) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Bi(1) and two equivalent Bi(4) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to one Bi(1), one Bi(2), and one Bi(4) atom. In the fifth O site, O(5) is bonded to one Pb(1), one Bi(2), one Bi(3), and one Bi(4) atom to form distorted corner-sharing OBi3Pb tetrahedra. In the sixth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one Bi(2) and two equivalent Bi(3) atoms. In the seventh O site, O(7) is bonded in a trigonal planar geometry to one Bi(1), one Bi(3), and one Bi(4) atom. is represented by the CIF card [CIF]
