چکیده
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 mol-ecule is stabilized by an intra-molecular C-H⋯O inter-action. In the crystal, the anion and cation are linked by an N-H⋯Cl hydrogen bond. Pairs of weak C-H⋯O and C-H⋯Cl hydrogen bonds form inversion dimers. Further N-H⋯Cl hydrogen bonds form R 2 (1)(6) motifs and link the dimers into chains along [101]. Br⋯Cl short contacts [3.482 (2) Å] inter-link the hydrogen-bonded chains along the b-axis direction.
