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 π–π interaction [ring centroid separation = 3.6212 (16) Å] and a C—Clπ interaction [Clring centroid = 3.4754 (8) Å]. In addition, short ClCl contacts [3.3767 (11) and 3.3946 (11) Å] are present.

In the asymmetric unit of the title compound {systematic name: N′-(2,4-dimethylphenyl)-N-[N-(2,4-dimethylphenyl)carboximidoyl]-N-methylmethanimidamide}, C19H23N3, which is a formamidine pesticide, there are two independent and conformationally similar molecules, with the dihedral angle between the mean planes of the 2,4-dimethylbenzene rings in each molecule being 41.63 (6) and 42.09 (5)°. The crystal structure is stabilized by a C—HN hydrogen bond, as well as weak intermolecular C—Hπ and π–π interactions [ring centroid separation = 3.7409 (15) Å], giving one-dimensional chains extending down the b direction.
