Abstract: The title complex, [HgBr₂L] [L is 1,4-bis(ethylsulfanyl)butane, C₄H₉S], has a dinuclear structure in which one L ligand links two HgBr₂ units. A C₂ symmetry axis passes through the centre of the ligand L. The Hg^II centre adopts a slightly distorted trigonal planar geometry coordinated by two Br^- anions and one S atom from L. When two weak Hg-Br interactions are considered, the dinuclear structure expands into a two-dimensional layer containing [HgBr₂]_n chains, with the Hg^II ion having a trigonal-bipyramidal geometry and the Br^- anion acting as a ₂ linkage.
