Crystal structure of 4-amino-1-(4-methylbenzyl)pyridinium bromide

Abstract

The title molecular 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 tetramer-like unit enclosing an R84(16) ring motif. These units are linked via C-H⋯Br hydrogen bonds, forming a three-dimensional network.
