6-bromo-2-(4-chlorophenyl)-3-((1-octyl-1H-1,2,3-triazol-4-yl)methyl)-3H-imidazo[4,5-b] pyridine, is built up from the 4-chlorophenyl and imidazo[4,5-b]pyridine ring system linked through a methylene bridge to a 1,2,3-triazole ring, which in turn also carries a substituent. The planar imidazo[4,5-b]pyridine ring is inclined by 19.37(12)° and 889.27(13)° to the phenyl and triazole rings, respectively, while phenyl and triazole rings are oriented at a dihedral angle of 71.23(15)°. In the crystal, the molecules are linked via intermolecular C— HTrz···NTrz (Trz = triazole) hydrogen bonds, enclosing R3 3 (21) and R3 3 (22) ring motifs, they are further linked through the bifurcated intermolecular C—HTrz···NTrz hydrogen bonds into a network consisting of double-column structure running along the b-axis direction. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H ··· H (57.2%), H ··· N/N ··· H (17.6%), H ··· C/C ··· H (9.6%), H ··· Cl/Cl ··· H (7.9%) and H ··· Br/Br ··· H (7.0%) interactions. No significant π ··· π or C–H ··· π interactions are observed.
