Crystal structure and Hirshfeld surface analysis of 4-azido-2-(3,5-di-methyl-phen-yl)-5-(4-nitro-phen-yl)-2 H -1,2,3-triazole.

In the title compound, C 16 H 13 N 7 O 2 , the 3,5-di-methyl-phenyl and 4-nitro-phenyl rings are inclined to the central 2 H -1,2,3-triazole ring by 1.80 (7) and 1.79 (7)°, respectively, and to one another by 2.16 (7)°. In the crystal, the mol-ecules are linked by C-H⋯N hydrogen bonds and π-π stacking inter-actions [centroid-to-centroid distances = 3.7295 (9) and 3.7971 (9) Å], forming ribbons along the b -axis direction. These ribbons are connected to each other by weak van der Waals inter-actions and the stability of the crystal structure is ensured. A Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H⋯H (31.5%), N⋯H/H⋯N (19.2%), O⋯H/H⋯O (14.5%), N⋯C/C⋯C (10.9%) and C⋯H/H⋯C (10.2%) contacts.
