N,N'-Bis[(E)-(2-chloro-8-methyl-quinolin-3-yl)methyl-idene]ethane-1,2-diamine
Abstract:
The complete mol-ecule of the title compound, C(24)H(20)Cl(2)N(4), is generated by a crystallographic inversion centre. A kink in the mol-ecule is evident [C-N-C-C torsion angle = -147.0 (3)°] owing to the twist in the central ethyl-ene 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 supra-molecular chains propagating in [010].
