catena-Poly[[bromomercury(II)]-di-μ-bromo-κ4Br:Br-[bromomercury(II)]-μ-1,4-bis(benzylsulfanyl)butane-κ2S:S′]

The title complex, [Hg2Br4(C18H22S2)](n), has a chain structure. Two bridging Br atoms and two terminal Br atoms coordinate to two Hg-II atoms to form a (HgBr2)(2) dimer, and the 1,4-bis( benzylsulfanyl) butane ligands bridge the ( HgBr2)(2) dimers to form a one-dimensional chain. The dimer and butane ligand are each located on inversion centers. Hg-II adopts a tetrahedral geometry formed by three Br and one S atoms.
