title: (E)-1-(4-Nitro-benzyl-idene)-2,2-diphenyl-hydrazine.
abstract: The asymmetric unit of the title compound, C(19)H(15)N(3)O(2), contains two mol-ecules, both of which show an E conformation of the imine bond. The dihedral angles between the phenyl rings in the phenyl-hydrazine groups are 86.09 (6) and 83.41 (5)° in the two mol-ecules. 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 inter-actions and C-H⋯O hydrogen bonds are observed growing along the a, b and c axes, resulting in a complex supramolecular array.
