Abstract: The title compound, C₁₉H₂₀Cl₂N₂, is a potential bidentate Schiff base ligand. Intramolecular C-HN hydrogen bonds form five-membered rings, generating S(5) ring motifs. Each imino functional group is coplanar with its adjacent benzene ring; the two benzene rings form a dihedral angle of 51.30 (4)°. An interesting feature of the crystal structure is weak intermolecular ClCl [3.4752 (4) Å] and ClN [3.2927 (9) Å] interactions. Intermolecular ClN interactions link molecules into dimers with R₂²(22) ring motifs. The crystal structure is further stabilized by weak - [centroid-centroid distances = 3.6970 (6)-3.8560 (6) Å] interactions.
