AgHgSI crystallizes in the orthorhombic Pmma space group. Ag(1) is bonded to two equivalent S(1), one I(1), and one I(2) atom to form a mixture of distorted edge and corner-sharing AgS2I2 trigonal pyramids. 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 I(2) 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 Ag(1), one Hg(1), and one Hg(2) atom to form corner-sharing SAg2Hg2 tetrahedra. There are two inequivalent I sites. In the first I site, I(1) is bonded in a 2-coordinate geometry to two equivalent Ag(1) atoms. In the second I site, I(2) is bonded in a 4-coordinate geometry to two equivalent Ag(1) and two equivalent Hg(1) atoms.
