Abstract: In the title molecular salt, C19H18BrClN3O2+·Cl-, the dihedral angles between the pyrimidine ring and the chlorobenzene and bromobenzene rings are 72.4 (2) and 45.5 (2)°, respectively. The dihedral angle between the chlorobenzene and bromobenzene rings is 27.5 (2)°. The conformation of the molecule is stabilized by an intramolecular C-HO interaction. In the crystal, the anion and cation are linked by an N-HCl hydrogen bond. Pairs of weak C-HO and C-HCl hydrogen bonds form inversion dimers. Further N-HCl hydrogen bonds form R21(6) motifs and link the dimers into chains along . BrCl short contacts [3.482 (2) Å] interlink the hydrogen-bonded chains along the b-axis direction.
