(E)-5-[(2-fluorophenyl)diazenyl]-2-hydroxy-3-methoxybenzaldehyde

Abstract

The title compound, C14H11FN2O3, displays the characteristic features of azobenzene derivatives. Intramolecular O - H center dot center dot center dot O and weak pi - pi interactions influence the conformation of the molecules and the crystal packing. The azobenzene moiety of the molecule has a trans configuration and the dihedral angle between the planes of the two aromatic rings is 10.13 (8)degrees.
