Abstract
In the structure of the title compound, C(10)H(11)BrN(4), the plane of the substituted 1,2,3-triazole ring is tilted by 14.84 (10)degrees with respect to the mean plane of the pyridine ring. The pyridine and closest triazole N atoms adopt an anti arrangement which removes any lone pair-lone pair repulsions between the N atoms. This conformation is further stabilized by weak intermolecular C-H center dot center dot center dot N interactions. There are two molecules in the unit cell, which form a centrosymmetric head-to-tail dimer. The dimers are stabilized through pi-pi interactions [centroid-centroid distance = 3.733 (4) angstrom and mean interplanar distance = 3.806 (12) angstrom] between the substituted 1,2,3-triazole ring and the pyridine rings in adjacent molecules. Each dimer interacts with two neighbouring dimers above and below, forming a slipped stack of dimers through the crystal. The 3-bromopropyl chain sits over the pyridine ring of a neighbouring molecule and the triazole rings of nearby molecules are adjacent.
