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)° 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⋯N inter-actions. There are two mol-ecules in the unit cell, which form a centrosymmetric head-to-tail dimer. The dimers are stabilized through π-π inter-actions [centroid-centroid distance = 3.733 (4) Å and mean inter-planar distance = 3.806 (12) Å] between the substituted 1,2,3-triazole ring and the pyridine rings in adjacent mol-ecules. Each dimer inter-acts with two neighbouring dimers above and below, forming a slipped stack of dimers through the crystal. The 3-bromo-propyl chain sits over the pyridine ring of a neighbouring mol-ecule and the triazole rings of nearby mol-ecules are adjacent.
