(E)-5-(4-Chlorophenyldiazenyl)salicylaldehyde

Abstract

The molecule of the title compound, C13H9ClN2O2, is approximately planar and displays a trans configuration with respect to the central N=N double bond. The dihedral angle between the two aromatic rings is 3.69 (14)°. The mol­ecules are linked by inter­molecular O—H⋯O hydrogen bonds, forming a two‐dimensional network.
