N,N′-Bis(4-chlorobenzylidene)-3,3′-dimethoxybiphenyl-4,4′-diamine

The title compound, C28H22Cl2N2O2, crystallized with two independent molecules (A and B) in the asymmetric unit. The two molecules differ essentially in the orientation of the outer aromatic rings. These dihedral angles are 56.07 (13) and 27.62 (15) Å for molecules A and B, respectively. In the crystal, A molecules are related as centrosymmetric pairs through a weak π–π interaction [centroid–centroid distance = 3.6959 (15) Å]. There are also a number of intermolecular C—H...O, C—H...N and C—H...π interactions present
