Hg6S4BrCl2Br crystallizes in the monoclinic C2/m space group. The structure consists of four hydrogen bromide atoms inside a Hg6S4BrCl2 framework. In the Hg6S4BrCl2 framework, there are five 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 Cl(1), and one Cl(2) atom. In the second Hg site, Hg(2) is bonded in a 3-coordinate geometry to two equivalent S(2) and two equivalent Cl(1) atoms. In the third Hg site, Hg(3) is bonded in a linear geometry to two equivalent S(1) and two equivalent Br(1) atoms. In the fourth Hg site, Hg(4) is bonded in a T-shaped geometry to two equivalent S(1) and one Cl(2) atom. In the fifth Hg site, Hg(5) is bonded in a linear geometry to two equivalent S(2) and two equivalent Br(1) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a distorted T-shaped geometry to one Hg(1), one Hg(3), and one Hg(4) atom. In the second S site, S(2) is bonded in a distorted T-shaped geometry to one Hg(1), one Hg(2), and one Hg(5) atom. Br(1) is bonded in a 4-coordinate geometry to two equivalent Hg(3) and two equivalent Hg(5) atoms. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 4-coordinate geometry to two equivalent Hg(1) and two equivalent Hg(2) atoms. In the second Cl site, Cl(2) is bonded in a trigonal planar geometry to one Hg(4) and two equivalent Hg(1) atoms.
