The structure described by HgSO4 crystallizes in the orthorhombic Pmn2_1 space group. Hg(1) is bonded in a 4-coordinate geometry to one O(2), one O(3), and two equivalent O(1) atoms. S(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Hg(1) and one S(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Hg(1) and one S(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Hg(1) and one S(1) atom. is represented by the CIF card [CIF]
