1,4-Bis{(+)-(S)-[1-(1-naphth-yl)eth-yl]imino-meth-yl}benzene
Abstract:
The title compound, C(32)H(28)N(2), is a chiral bis-imine in which both imine groups display the common E configuration. The naphthyl groups present different orientations with respect to the central core, as reflected in the dihedral angles of 21.4 (2) and 78.83 (14)° between the benzene and naphthyl mean planes, thus the highest possible C(2) local molecular symmetry is not attained. This C(1) mol-ecular conformation allows multiple C-H⋯π inter-molecular contacts involving all aromatic rings, while no π-π inter-actions are available for the stabilization of the crystal structure. The resulting packing structure is based on mol-ecules stacked along [100].

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...
