2-Amino-5-bromo-pyridin-1-ium (2-amino-5-bromo-pyridine-?N (1))trichloridozincate.

ABSTRACT: The structure of the title salt, (C5H6BrN2)[ZnCl3(C5H5BrN2)], consists of discrete 2-amino-5-bromo-pyridin-1-ium cations and distorted tetra-hedral (2-amino-5-bromo-pyridine)-tri-chlorido-zincate 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 ?-? stacking inter-actions between the pyridine and pyridinium rings, with alternating centroid-to-centroid distances of 3.653?(2) and 3.845?(2)?Å.
