PbSeO4 crystallizes in the monoclinic P2_1/c space group. Pb(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Se(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Pb(1) and one Se(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Pb(1) and one Se(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Pb(1) and one Se(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Pb(1) and one Se(1) atom.
