title: Crystal structure of 4-amino-1-(4-methyl-benz-yl)pyridinium bromide.
abstract: The title mol-ecular salt, C13H15N2 (+)·Br(-), crystallized with two independent ion pairs (A and B) in the asymmetric unit. In the cations, the planes of the pyridine and benzene rings are inclined to one another by 79.32 (8) and 82.30 (10)° in ion pairs A and B, respectively. In the crystal, the anions and cations are connected by N-H⋯Br hydrogen bonds, forming a centrosymmetric tetra-mer-like unit enclosing an R 8 (4)(16) ring motif. These units are linked via C-H⋯Br hydrogen bonds, forming a three-dimensional network.
