(E)-1-Benzyl­idene-2,2-diphenyl­hydrazine

The asymmetric unit of the title compound, C₁₉H₁₆N₂, contains two independent mol­ecules, both of which show an E configuration with respect to the C=N bond. The dihedral angles between the phenyl rings bonded to the hydrazine group are 81.00 (10) and 88.34 (8)° in the two mol­ecules. Inter­molecular C—H...π inter­actions are observed in the crystal structure.

(E)-1-(4-Nitro­benzyl­idene)-2,2-diphenyl­hydrazine

The asymmetric unit of the title compound, C₁₉H₁₅N₃O₂, contains two mol­ecules, both of which show an E conformation of the imine bond. The dihedral angles between the phenyl rings in the phenyl­hydrazine groups are 86.09 (6) and 83.41 (5)° in the two mol­ecules. The 4-nitrobenzene rings show torsion angles of 4.4 (2) and 10.9 (2)° from the two C=N—N planes. In the crystal, C—H...π inter­actions and C—H...O hydrogen bonds are observed growing along the a, b and c axes, resulting in a complex supramolecular array.
