Abstract: The crystal structure of the title compound, C₄H₁₂N₅⁺·Br^-, shows that the C-N bonds in this compound range in length from 1.316  (4) to 1.354  (4)  Å. The dihedral angle between the two guanide planes is 68.5  (1)°. The crystal packing is stabilized by N-HN and N-HBr hydrogen bonds. The bromide anions are involved in six hydrogen bonds and are sandwiched between layers of N,N-dimethylbiguanidium cations.
