N,N'-Bis(4-chloro-benzyl-idene)-3,3'-dimeth-oxy-biphenyl-4,4'-diamine
Abstract:
The title compound, C(28)H(22)Cl(2)N(2)O(2), crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The two mol-ecules differ essentially in the orientation of the outer aromatic rings. These dihedral angles are 56.07 (13) and 27.62 (15) Å for mol-ecules A and B, respectively. In the crystal, A mol-ecules are related as centrosymmetric pairs through a weak π-π inter-action [centroid-centroid distance = 3.6959 (15) Å]. There are also a number of inter-molecular C-H⋯O, C-H⋯N and C-H⋯π inter-actions present.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
