The crystal structure of dibromamine-T, an important brominating/oxidising agent, which crystallizes in the monoclinic space group P21/c with cell parameters a = 10.325(3)Å, b = 8.281 (2) Å, c = 12.611 (5) Å ,β = 102.44(3)° and Z = 4 has been solved using DlRDIF programme and refined using SHELXL. The structure shows both intramolecular and intermolecular hydrogen bonds of the type CH .... O. The molecules are arranged in layers
