1-(3-Bromo­prop­yl)-4-(2-pyrid­yl)-1H-1,2,3-triazole

In the structure of the title compound, C10H11BrN4, 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 inter­actions. There are two mol­ecules in the unit cell, which form a centrosymmetric head-to-tail dimer. The dimers are stabilized through π–π inter­actions [centroid–centroid distance = 3.733 (4) Å and mean inter­planar distance = 3.806 (12) Å] 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
