N,N′-Bis(4-chloro­benzyl­idene)-2,2-dimethyl­propane-1,3-diamine

The title compound, C(19)H(20)Cl(2)N(2), is a potential bidentate Schiff base ligand. Intra­molecular C—H⋯N 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 Cl⋯Cl [3.4752 (4) Å] and Cl⋯N [3.2927 (9) Å] inter­actions. Inter­molecular Cl⋯N inter­actions link mol­ecules into dimers with R(2)(2)(22) ring motifs. The crystal structure is further stabilized by weak π–π [centroid–centroid distances = 3.6970 (6)–3.8560 (6) Å] inter­actions.
