The structure described by CrHg3(SO2)2 crystallizes in the monoclinic P2_1/c space group. Cr(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are three inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 4-coordinate geometry to one S(1), one S(2), one O(1), and one O(3) atom. In the second Hg site, Hg(2) is bonded in a distorted rectangular see-saw-like geometry to one S(1), one S(2), one O(1), and one O(4) atom. In the third Hg site, Hg(3) is bonded in a distorted rectangular see-saw-like geometry to one S(1), one S(2), one O(2), and one O(3) atom. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 3-coordinate geometry to one Hg(1), one Hg(2), and one Hg(3) atom. In the second S site, S(2) is bonded in a distorted trigonal non-coplanar geometry to one Hg(1), one Hg(2), and one Hg(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Cr(1), one Hg(1), and one Hg(2) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Cr(1) and one Hg(3) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Cr(1), one Hg(1), and one Hg(3) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Cr(1) and one Hg(2) atom. is represented by the CIF card [CIF]
