Abstract: The structure of the title salt, (C5H6BrN2)[ZnCl3(C5H5BrN2)], consists of discrete 2-amino-5-bromo­pyridin-1-ium cations and distorted tetra­hedral (2-amino-5-bromo­pyridine)­tri­chlorido­zincate anions. In the crystal, the complex anions and cations are linked via N-H...Cl hydrogen bonds into layers parallel to (101). Short Br...Cl contacts of 3.4239 (11) and 3.4503 (12) Å are observed, as well as [pi]-[pi] stacking inter­actions between the pyridine and pyridinium rings, with alternating centroid-to-centroid distances of 3.653 (2) and 3.845 (2) Å.
