Abstract :
The title compound, C16H14Cl3N3, comprises three molecules of similar shape in the asymmetric unit. The crystal cohesion is ensured by intermolecular C—H⋯N and C—H⋯Cl hydrogen bonds in addition to C—Cl⋯π interactions. Hirshfeld surface analysis and two-dimensional fingerprint plots reveal that Cl⋯H/H⋯Cl (33.6%), H⋯H (27.9%) and C⋯H/H⋯C (17.6%) are the most important contributors towards the crystal packing.
