Crystal structure of (E)-2-{[(4-anilinophenyl)imino]methyl}-4-nitrophenol

Abstract

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 intramolecular 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 interactions to generate (001) sheets.
