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—H...O and O—H...F 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—H...O 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—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—Cl...π inter­action [Cl...ring centroid = 3.4754 (8) Å]. In addition, short Cl...Cl contacts [3.3767 (11) and 3.3946 (11) Å] are present.

The title compound [systematic name: N,N-diethyl-2-(naphthalen-1-yl­oxy)propanamide], C17H21NO2, crystallizes with two independent mol­ecules in the asymmetric unit in which the dihedral angles between the naphthalene ring systems and the amide groups are 88.1 (9) and 88.7 (3)°. Four C—H...O hydrogen bonds stabilize the crystal structure.

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—H...N hydrogen bond, as well as weak inter­molecular C—H...π 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—H...F hydrogen bonds link the mol­ecules into inversion dimers which are linked by C—Cl...π [Cl...ring centroid = 3.3618 (4) A °] and N—O...π [O...ring centroid = 3.1885 (16) Å] inter­actions into chains along [100]. In addition, short Cl...Cl, O...Cl, and F...F contacts [3.4676 (7), 3.2371 (13) and 2.7910 (15) Å] are present which connect the chains, yielding a three-dimensional network.
