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 WO6 octahedra that share corners with four equivalent W(1)O6 octahedra, corners with four equivalent Pb(1)O6 octahedra, and  an edgeedge with one Pb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 3-68°. Pb(1) is bonded to three equivalent O(2) and three equivalent O(3) atoms to form distorted PbO6 octahedra that share corners with four equivalent W(1)O6 octahedra,  an edgeedge with one W(1)O6 octahedra, and edges with six equivalent Pb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 57-68°. 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 edge and corner-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 edge and corner-sharing OPb3W tetrahedra. In the fourth O site, O(4) is bonded in a linear geometry to two equivalent W(1) atoms.
