Abstract: The title compound 2-chloroazobenzene-2-sulphenylbromide (I) (C12H8BrClN2S) is ionic in nature. The electronegativity difference between S and Br atoms makes S atom electrophilic in nature and the presence of intramolecular interaction between the S atom and the azo group has been established by the formation of bond between S and N5 atom and increase in the bond distance between S and Br atoms to 3.23 1 (7)Å in the compound, which is greater than any known covalent length between them. The dihedral angle between the phenyl rings A and C is 46.13(0.13)0. The molecules are stabilised by the network of intermolecular hydrogen bonds and van der Waals contacts.
