In the title molecular salt, C20H19BrF2N3O2+·NO3−, the N atom at position 4 of the heterocyclic ring is protonated. The triazole ring makes dihedral angles of 96.6 (4) and 54.4 (3)° with the 4-bromophenyl and 2,4-difluorophenyl rings, respectively, and the molecule adopts a Z conformation about the C=C double bond. In the crystal, cations and anions are linked by N—H⋯O and C—H⋯O hydrogen bonds.
