RESUMEN
Colourless crystals of the title compound, bis(2-bromophenyl) disulfide, C(12)H(8)Br(2)S(2), are obtained from the reaction of 2-bromophenylmercaptan with metallic sodium and either zinc chloride or cadmium chloride in methanol. In the presence of Zn(II) ions, the crystals are orthorhombic (space group Pbca, with Z' = 1); with Cd(II) ions present, the product is triclinic (space group (-)P1, with Z' = 4). Both polymorphs exhibit significant intramolecular C-H.S hydrogen bonds. In the orthorhombic form, molecules are linked by intermolecular C-H...Br hydrogen bonds, while in the triclinic form, molecules exhibit Br...Br contacts.
