Coordination Assemblies of Acetylenic Dithioether Ligands on Silver(I) Salts: Crystal Structure, Antibacterial and Cytotoxicity Activities.

Coordination polymers (CPs) and metal-organic frameworks (MOFs) constitute a new class of antibacterial materials. Interest in them stems from their wide range of topology, dimensionality, and secondary building units that can be tuned by an appropriate choice of metal ions and ligands. In particular, silver-based species feature good antibacterial properties.

The Halogen Bond to Ethers - Prototypic Molecules and Experimental Electron Density.

Halogen bonds to dialkyl ether molecules have remained largely unexplored. We here address the synthesis and the structural chemistry of the first halogen-bonded noncyclic alkyl ethers, combining 1,4-diiodotetrafluorobenzene and the prototypic or commonly used ethers dimethyl ether, tetrahydrofuran, and methyl--butyl ether as halogen acceptors. Two different structural motifs based on moderately strong halogen bonds were obtained: Discrete trimolecular aggregates are formed, and unexpected halogen-bonded supramolecular chain adducts feature oxygen-bifurcated halogen bonds with 1:1 donor:acceptor ratio.

Crystal structure and Hirshfeld surface analysis of a halogen bond between 2-(allyl-thio)-pyridine and 1,2,4,5-tetra-fluoro-3,6-di-iodo-benzene.

The crystal structure of the title 2:1 mol-ecular complex between 2-(allyl-thio)-pyridine and 1,2,4,5-tetra-fluoro-3,6-di-iodo-benzene, CFI·2CHNS, at 100 K has been determined in the monoclinic space group 2/. The most noteworthy characteristic of the complex is the halogen bond between iodine and the pyridine ring with a short N⋯I contact [2.8628 (12) Å].

Crystal structure and Hirshfeld surface analysis of dimeth-yl(phen-yl)phosphine sulfide.

The title compound, CHPS, which melts below room temperature, was crystallized at low temperature. The P-S bond length is 1.9623 (5) Å and the major contributors to the Hirshfeld surface are H⋯H (58.
