Abstract:
In the title compound, C29H20N2, the dihedral angles subtended by the central p-phenyl-enedi-amine ring with respect to the mean plane of the terminal pyrenyl ring system (r.m.s. deviation = 0.027 Å) and the terminal N-phenyl ring are 29.34 (4) and 43.43 (7)°, respectively. The conformation about the C=N bond is E. In the crystal, mol-ecules are linked by N-H⋯π and C-H⋯π inter-actions forming chains propagating along the [10-2] direction. These chains are linked via π-π inter-actions [inter-centroid distances are in the range 3.5569 (11)-3.708 (1) Å], forming slabs lying parallel to (30-4).

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...
