The material described by CuHgSCl crystallizes in the orthorhombic Pmma space group. Cu(1) is bonded to two equivalent S(1), one Cl(1), and one Cl(2) atom to form a mixture of distorted corner and edge-sharing CuS2Cl2 tetrahedra. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent S(1) and two equivalent Cl(1) atoms. In the second Hg site, Hg(2) is bonded in a linear geometry to two equivalent S(1) atoms. S(1) 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 L-shaped geometry to two equivalent Cu(1) and two equivalent Hg(1) atoms. In the second Cl site, Cl(2) is bonded in an L-shaped geometry to two equivalent Cu(1) atoms. is represented by the CIF card [CIF]
