(E)-1-(2-Nitrobenzylidene)-2-phenylhydrazine

The asymmetric unit of the title compound, C13H11N3O2, contains two molecules with slightly different conformations: the dihedral angle between the aromatic rings is 13.01 (10)° in one molecule and 14.05 (10)° in the other. Both molecules feature short intramolecular C—H...O contacts, which generate S(6) rings. In the crystal, both molecules form inversion dimers linked by pairs of N—H...O hydrogen bonds, thereby generating R22(16) rings.
