N,N′-Bis[(E)-(2-chloro-8-methyl­quinolin-3-yl)methyl­idene]ethane-1,2-diamine

The complete mol­ecule of the title compound, C(24)H(20)Cl(2)N(4), is generated by a crystallographic inversion centre. A kink in the mol­ecule is evident [C—N—C—C torsion angle = −147.0 (3)°] owing to the twist in the central ethyl­ene bridge. Further, there is a small twist between the imine [N=C = 1.267 (3) Å] and quinoline residues [N—C—C—C = −12.4 (4)°]. In the crystal, a combination of π–π [pyridine–benzene centroid–centroid distance = 3.5670 (14) Å] and C—H⋯N contacts leads to supra­molecular chains propagating in [010].
