The structure described by PbWO4 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(4), one O(5), one O(7), and two equivalent O(8) atoms to form a mixture of distorted edge and corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 22-34°. In the second W site, W(2) is bonded to one O(2), one O(5), one O(6), one O(7), and two equivalent O(3) atoms to form a mixture of distorted edge and corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 22-34°. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 7-coordinate geometry to one O(1), one O(3), one O(4), one O(5), one O(6), one O(7), and one O(8) atom. In the second Pb site, Pb(2) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(6), and one O(8) atom. There are eight inequivalent O sites. In the first O site, O(5) is bonded in a 3-coordinate geometry to one W(1), one W(2), and one Pb(1) atom. In the second O site, O(6) is bonded in a distorted single-bond geometry to one W(2), one Pb(1), and one Pb(2) atom. In the third O site, O(7) is bonded in a distorted bent 150 degrees geometry to one W(1), one W(2), and one Pb(1) atom. In the fourth O site, O(8) is bonded to two equivalent W(1), one Pb(1), and one Pb(2) atom to form edge-sharing OPb2W2 tetrahedra. In the fifth O site, O(1) is bonded in a 3-coordinate geometry to one W(1), one Pb(1), and one Pb(2) atom. In the sixth O site, O(2) is bonded in a distorted bent 120 degrees geometry to one W(2) and one Pb(2) atom. In the seventh O site, O(3) is bonded in a 4-coordinate geometry to two equivalent W(2), one Pb(1), and one Pb(2) atom. In the eighth O site, O(4) is bonded in a distorted single-bond geometry to one W(1), one Pb(1), and one Pb(2) atom. is represented by the CIF file [CIF]
