The synthesis, crystal structure, and some spectroscopic details for the phenylpyrazole-based insecticide N-{3-cyano-1-[2,6-dichloro-4- (trifluoromethyl)phenyl]-4-(ethylsulfanyl)-1H-pyrazol-5-yl}-2,2,2- trifluoroacetamide (C15H8N4Cl2F6OS) are presented.

Three hexahydroquinoline derivatives were synthesized and crystallized in an effort to study the structure–activity relationships of these calcium-channel antagonists. n these hexahydroquinoline derivatives, common structural features such as a flat-boat conformation of the 1,4-dihydropyridine (1,4-DHP) ring, an envelope conformation of the fused cyclohexanone ring, and a substituted phenyl group at the pseudo-axial position are retained. Hydrogen bonds are the main contributors to the packing of the molecules in these crystals.

In the crystal structure of the title compound, the Ni cations are octahedrally coordinated and linked into chains that are arranged in such a way that channels are formed in which acetonitrile solvate molecules are embedded that can reversibly be removed.

4,5-Dimethyl-1,3-dioxol-2-one crystallizes on a mirror plane in P21/m and forms layered sheets that comprise antiparallel linear strands. Close O⋯H, C⋯O and C⋯C intermolecular contacts are formed between strands and sheets.

The title compound, a charge-neutral bis{2-(3,4-dimethylphenyl)-4H-1,2,4-triazol-3-ato)-6-(1H-πyrazol-1-yl)pyridine} iron(II) complex dimethanol solvate, is a low-spin complex with a moderately distorted pseudooctahedral coordination environment of the metal ion. As a result of the cone shape, the molecules are stacked in mono-periodic columns that are bound by weak hydrogen bonds into di-periodic layers, which, in turn, are arranged in a three-dimensional lattice bound by weak interlayer interactions.

The title compound crystallizes in the triclinic space group P with a monomeric [Co(3-meo-cin)(phen)2(H2O)]+ cation and a nitrate anion (3-meo-cin = 3-methoxy cinnamic acid) in the asymmetric unit. The CoII ion is coordinated by four N atoms from two 1,10-phenanthroline ligands and two O atoms, the first from a methoxy cinnamate ligand and the second from a coordinated water molecule, forming a distorted octahedral geometry.

In the title compound, the dihedral angle between the mean planes of the cyclohexane and 1,3-dithietane rings is 9.1 (3)°. A short S⋯O contact is observed in the crystal.

The coordination polyhedra of the complex cations in the one-dimensional coordination polymers I and II represent tetragonally distorted NiN4O2 octahedra with the four N atoms of the azamacrocyclic cyclam ligand in the equatorial planes and two O atoms of the benzenetricarboxylate anions in the axial positions. The crystals of both compounds are composed of parallel coordination polymeric chains running along the [010] direction in I and the [110] and [10] directions in II. As a result of hydrogen-bonding interactions, the chains are joined together in layers oriented parallel to the (10) and (001) planes in I and II, respectively.

The title charge-neutral complex is a low-spin complex with a moderately distorted pseudo-octahedral coordination environment of the metal ion. As a result of their asymmetric shape, the molecules stack into chains, which eventually pack into layers and, finally, into a three-dimensional network connected by weak C—H⋯N, C—H⋯C hydrogen bonds and C—H⋯π interactions.
