The crystal structure described by PbWO4 crystallizes in the monoclinic P2_1/c space group. W(1) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 8-10°. Pb(1) is bonded in a 6-coordinate geometry to three equivalent O(2) and three equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent W(1) atoms. In the second O site, O(2) is bonded to one W(1) and three equivalent Pb(1) atoms to form a mixture of distorted corner and edge-sharing OPb3W tetrahedra. In the third O site, O(3) is bonded to one W(1) and three equivalent Pb(1) atoms to form a mixture of distorted corner and edge-sharing OPb3W tetrahedra. In the fourth O site, O(4) is bonded in a linear geometry to two equivalent W(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
