In the title compound, [Cd(C8F4O4)(C2H5OH)2]n, the CdII cation sits on an inversion centre and is coordinated by six O atoms from four tetrafluorobenzene-1,4-dicarboxylate anions and two ethanol molecules in a distorted octahedral geometry. The anionic ligand is also located on an inversion centre, and connects four CdII cations, generating a two-dimensional polymeric layer parallel to the ab plane. Within the layer, the ethanol molecule links F and O atoms of the nearest anionic ligands via O—HO and O—HF hydrogen bonds. The ethyl group of the ethanol molecule is disordered over two positions with an occupancy ratio of 0.567 (10):0.433 (10).

In the title compound, [Co(C12H12O4)(C5H5N)2]n, the CoII cation is coordinated by four O atoms from three 5-tert-butylbenzene-1,3-dicarboxylate anions and two N atoms from pyridine molecules in a distorted octahedral geometry. One carboxylate group of the anionic ligand chelates a CoII cation while another carboxylate group bridges two CoII cations, resulting in a polymeric layer parallel to (101). Weak C—HO hydrogen bonds occur between adjacent polymeric layers. In the crystal, one of pyridine molecules is equally disordered over two positions.

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.

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.
