Abstract: In the title compound, C12H11BrN5+·Cl-, the cation exists as the N3-protonated N7 tautomer. The crystal structure is stabilized by N-HCl hydrogen bonds, which connect cations and anions into linear chains along the  direction. There are also some additional - stacking interactions and weak interatomic contacts of the types CCl and CBr.
