CuHgSCl crystallizes in the orthorhombic Pbam space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to two equivalent S(2), one Cl(1), and one Cl(2) atom to form corner-sharing CuS2Cl2 tetrahedra. In the second Cu site, Cu(2) is bonded in a distorted trigonal planar geometry to two equivalent S(1) and one Cl(1) atom. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a distorted rectangular see-saw-like geometry to one S(1), one S(2), and two equivalent Cl(1) atoms. In the second Hg site, Hg(2) is bonded in a distorted rectangular see-saw-like geometry to one S(1), one S(2), and two equivalent Cl(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Cu(2), one Hg(1), and one Hg(2) atom to form corner-sharing SCu2Hg2 tetrahedra. In the second S site, S(2) is bonded to two equivalent Cu(1), one Hg(1), and one Hg(2) atom to form corner-sharing SCu2Hg2 trigonal pyramids. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted water-like geometry to one Cu(1), one Cu(2), and two equivalent Hg(1) atoms. In the second Cl site, Cl(2) is bonded in a distorted single-bond geometry to one Cu(1) and two equivalent Hg(2) atoms.
