Crystal structure of (E)-2-{[(4-anilinophen-yl)imino]meth-yl}-4-nitro-phenol.

In the title compound, C19H15N3O3, which crystallizes as the phenol-imine tautomer, the dihedral angle between the aromatic rings bridged by the NH unit is 47.16 (16)°. The dihedral angle between the rings bridged by the imine unit is 6.24 (15)°; this near coplanarity is reinforced by an intra-molecular O-H⋯N hydrogen bond, which generates an S(6) ring. In the crystal, N-H⋯O hydrogen bonds generate [201] C(13) chains. The chains are reinforced and cross-linked by C-H⋯O inter-actions to generate (001) sheets.
