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

Abstract

The crystal structure of a nitrophenol-derived Schiff base compound was determined. The molecule adopts the phenol-imine tautomeric form. The dihedral angle between the two aromatic rings connected through the NH bridge measures 47.16°, while the rings linked by the imine group are nearly coplanar at 6.24°. An intramolecular O-H···N hydrogen bond stabilizes this near-planar arrangement, forming an S(6) ring motif. In the solid state, intermolecular N-H···O hydrogen bonds propagate along the [201] direction to produce one-dimensional chains, which are further interconnected by C-H···O contacts to form two-dimensional sheets parallel to the (001) plane.
