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—H
O 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.

In the asymmetric unit of the title compound {systematic name: 3-chloro-N-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-2,6-dinitro-4-(trifluoromethyl)aniline}, C13H4Cl2F6N4O4, which is the fungicide fluazinam, the dihedral angle between the pyridine and benzene ring planes is 42.20 (4)°. In the crystal, pairs of N—HF hydrogen bonds link the molecules into inversion dimers which are linked by C—Clπ [Clring centroid = 3.3618 (4) A °] and N—Oπ [Oring centroid = 3.1885 (16) Å] interactions into chains along [100]. In addition, short ClCl, OCl, and FF contacts [3.4676 (7), 3.2371 (13) and 2.7910 (15) Å] are present which connect the chains, yielding a three-dimensional network.
