Crystal structure of catena-poly[[silver(I)-μ-N-(pyridin-2-ylmeth­yl)pyridine-3-amine-κ²N:N′] tri­fluoro­methane­sulfonate]

The reaction of Ag^I with the unsymmetrical ligand N-(pyridine-2-ylmeth­yl)pyridine-3-amine afforded right- and left-handed helical chains. The Ag^I atom of the right-handed helical chain adopts a slightly distorted linear coordination geometry, while that of the left-handed helical chain displays a bent geometry.

Vinclozolin: 3-(3,5-di­chloro­phen­yl)-5-ethenyl-5-methyl-1,3-oxazolidine-2,4-dione

In the title compound, C₁₂H₉Cl₂NO₃, which is the fungicide vinclozolin, the dihedral angle between the oxazolidine ring mean plane [r.m.s. deviation = 0.029 Å] and the benzene ring is 77.55 (8)°. In the crystal, mol­ecules are linked via C—H...O hydrogen bonds, forming chains along [010]. The chains are linked by short Cl...Cl contacts [3.4439 (3) and 3.5798 (3) Å], resulting in a three-dimensional architecture.

Diafenthiuron: 1-tert-butyl-3-(2,6-diisopropyl-4-phen­oxy­phen­yl)thio­urea

The title compound, C₂₃H₃₂N₂OS, is a thio­urea-based insecticide. The dihedral angle between the phenyl ring and the diisopropyl benzene ring plane is 73.18 (6)°, while that between the plane of the thio­urea group and the diisopropyl benzene ring is 86.00 (5)°. Disorder was modelled for the S atom and the two methyl C atoms of the isopropyl group over two sets of sites with an occupancy ratio of 0.742 (4):0.258 (4). In the crystal, N—H...S hydrogen bonds link adjacent mol­ecules, forming R₂²(8) inversion dimers that pack into chains along the b-axis direction.

Crystal structure of triclopyr

In the title compound {systematic name: 2-[(3,5,6-tri­chloro­pyridin-2-yl)­oxy]acetic acid}, the herbicide triclopyr, C₇H₄Cl₃NO₃, the asymmetric unit comprises two independent mol­ecules in which the dihedral angles between the mean plane of the carb­oxy­lic acid group and the pyridyl ring plane are 79.3 (6) and 83.8 (5)°. In the crystal, pairs of inter­molecular O—H...O hydrogen bonds form dimers through an R₂²(8) ring motif and are extended into chains along [100] by weak π–π inter­actions [ring centroid separations = 3.799 (4) and 3.810 (4) Å]. In addition, short inter­molecular Cl...Cl contacts [3.458 (2) Å] connect the chains, yielding a two-dimensional architecture extending parallel to (020). The crystal studied was found to be non-merohedrally twinned with the minor component being 0.175 (4).

Crystal structure of tolyl­fluanid

The title compound, C₁₀H₁₃Cl₂FN₂O₂S₂ {systematic name: N-[(di­chloro­fluoro­methyl)­sulfanyl]-N′,N′-dimethyl-N-p-tolyl­sulfamide}, is a well known fungicide. The dihedral angle between the mean plane of the di­methyl­amino group and that of the benzene ring is 32.3 (3)°. One Cl atom and one F atom of the di­chloro­fluoro­methyl­thio group are disordered over two sets of sites with an occupancy ratio of 0.605 (9):0.395 (9). In the crystal structure, two C—H...Cl hydrogen bonds link adjacent mol­ecules, forming dimers with R₂²(14) loops. C—H...O hydrogen bonds link pairs of dimers into chains along the b-axis direction. These chains are joined by an additional C—H...O contact, generating a sheet in the ab plane.

Crystal structure of 3,6-bis­(2-chloro­phen­yl)-1,2,4,5-tetra­zine: the acaricide clofentezine

The whole molecule of the title compound, C₁₄H₈Cl₂N₄, is generated by inversion symmetry. The dihedral angle between the 2-chloro­phenyl ring and the tetra­zine ring is 47.65 (5)°. In the crystal, mol­ecules are linked by slipped parallel π–π inter­actions [centroid–centroid distance = 3.8199 (5), normal distance = 3.3127 (8), slippage 1.902 Å] forming columns along the a-axis direction.

Crystal structure of difenoconazole

In the title compound difenoconazole [systematic name: 1-({2-[2-chloro-4-(4-chloro­phen­oxy)phen­yl]-4-methyl-1,3-dioxolan-2-yl}meth­yl)-1H-1,2,4-triazole], C₁₉H₁₇Cl₂N₃O₃, the dihedral angle between the planes of the 4-chloro­phenyl and 2-chloro­phenyl rings is 79.34 (9)°, while the dihedral angle between the planes of the triazole ring and the dioxolanyl group is 59.45 (19)°. In the crystal, pairs of C—H...N hydrogen bonds link adjacent mol­ecules, forming dimers with R₂²(6) loops. In addition, the dimers are linked by C—H...O hydrogen bonds, resulting in a three-dimensional architecture. Disorder was modeled for one C atom of the dioxolanyl group over two sets of sites with an occupancy ratio of 0.566 (17):0.434 (17).
