The material described by AgHgSBr crystallizes in the orthorhombic Pmma space group. Ag(1) is bonded to two equivalent S(1), one Br(1), and one Br(2) atom to form a mixture of distorted corner and edge-sharing AgS2Br2 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 Br(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 Ag(1), one Hg(1), and one Hg(2) atom to form corner-sharing SAg2Hg2 trigonal pyramids. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 4-coordinate geometry to two equivalent Ag(1) and two equivalent Hg(1) atoms. In the second Br site, Br(2) is bonded in a 2-coordinate geometry to two equivalent Ag(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
