HgSO4 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of eight HgSO4 clusters. Hg(1) is bonded in a single-bond geometry to one O(3) atom. S(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 single-bond geometry to one S(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one S(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Hg(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one S(1) atom.
