The structure described by Hg4Cd4S4Br3Br crystallizes in the orthorhombic Cmmm space group. The structure consists of two hydrogen bromide atoms inside a Hg4Cd4S4Br3 framework. In the Hg4Cd4S4Br3 framework, there are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a linear geometry to two equivalent S(1) atoms. In the second Hg site, Hg(2) is bonded in a linear geometry to two equivalent S(1) atoms. Cd(1) is bonded to two equivalent S(1), one Br(2), and two equivalent Br(1) atoms to form a mixture of distorted corner and edge-sharing CdS2Br3 square pyramids. S(1) is bonded in a rectangular see-saw-like geometry to one Hg(1), one Hg(2), and two equivalent Cd(1) atoms. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 4-coordinate geometry to four equivalent Cd(1) atoms. In the second Br site, Br(2) is bonded in a distorted square co-planar geometry to four equivalent Cd(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
