Crystal structure and Hirshfeld surface analysis of (E)-1-(2,6-di­chloro­phen­yl)-2-(2-nitro­benzyl­idene)hydrazine

In the title compound, C(13)H(9)Cl(2)N(3)O(2), the 2,6-di­chloro­phenyl ring and the nitro-substituted benzene ring form a dihedral angle of 21.16 (14)°. In the crystal, face-to-face π–π stacking inter­actions occur along the a-axis direction between the centroids of the 2,6-di­chloro­phenyl ring and the nitro-substituted benzene ring. Furthermore, these mol­ecules show intra­molecular N—H⋯Cl and C—H⋯O contacts and are linked by inter­molecular N—H⋯O and C—H⋯Cl hydrogen bonds, forming pairs of hydrogen-bonded mol­ecular layers parallel to (20[Image: see text]). The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H⋯H (23.0%), O⋯H/H⋯O (20.1%), Cl⋯H/H⋯Cl (19.0%), C⋯C (11.2%) and H⋯C/C⋯H (8.0%) inter­actions.
