In the title compound, the herbicide bifenox, C14H9Cl2NO5, the dihedral angle between the dichlorobenzene and nitrobenzene rings is 78.79 (14)°. In the crystal, C-HO hydrogen bonds give rise to a three-dimensional network structure in which there are both a - interaction [ring centroid separation = 3.6212 (16) Å] and a C-Cl interaction [Clring centroid = 3.4754 (8) Å]. In addition, short ClCl contacts [3.3767 (11) and 3.3946 (11) Å] are present.
