Towards Anion Recognition and Precipitation with Water-Soluble 1,2,4-Selenodiazolium Salts: Combined Structural and Theoretical Study

Alexey A. Artemjev et al.

Summary: The synthesis and structural characterization of supramolecular complexes of bicyclic cationic pyridine-fused 1,2,4-selenodiazoles with various anions are reported. The anions interact with the selenodiazolium cations through chelating non-covalent interactions, making them an attractive supramolecular recognition unit. The solubility and precipitation behavior of these complexes are discussed, and theoretical methods are used to study the nature and energies of the non-covalent interactions.

Supramolecular organic frameworks derived from bromoaryl-substituted dichlorodiazabutadienes via ClBr halogen bonding

Namiq G. Shikhaliyev et al.

Summary: Aryl-3-(4-bromophenyl)-4,4-dichloro-1,2-diazabuta-1,3dienes were synthesized through copper-catalyzed reaction, revealing non-covalent Cl???Br interactions and 3D supramolecular framework. Both X-ray diffraction analysis and theoretical calculations confirmed the presence of highly polarizable dichlorodiazadiene unit as a strong halogen bond donor within the framework.

Attractive fluorine•••fluorine interactions between perfluorinated alkyl chains: a case of perfluorinated Cu(II) diiminate Cu[C2F5-C(NH)-CF=C(NH)-CF3]2

Victor N. Khrustalev et al.

Summary: The study reports the synthesis of a perfluorinated copper diiminate complex and its self-assembly into infinite 1D chains in the crystal via Type II C(sp(3))-F···F-C(sp(3)) contacts between perfluoroethyl substituents. Rare Type II F···F interactions were investigated through DFT calculations and electron density analysis within Bader's theory, marking the first report to discuss Type II contacts between perfluoroalkyl chains.

Azoimidazole gold(III) complexes: Synthesis, structural characterization and self-assembly in the solid state

Alexander G. Tskhovrebov et al.

Summary: Novel triarylazoimidazole trichlorogold(III) complexes were prepared and characterized in this study. Structural characterization revealed weak coordination of the azo group to the gold(III) center. Additionally, non-covalent chlorine---chlorine interactions were observed in the solid state.

Novel cationic 1,2,4-selenadiazoles: synthesis via addition of 2-pyridylselenyl halides to unactivated nitriles, structures and four-center SeMIDLINE HORIZONTAL ELLIPSISN contacts

Victor N. Khrustalev et al.

Summary: 2-Pyridylselenyl halides undergo facile coupling with unactivated nitriles, leading to the preparation of a novel class of cationic 1,2,4-selenadiazoles in high yields. The cationic 1,2,4-selenadiazoles form supramolecular dimers in the crystal through Se-M chalcogen bonding, which has been studied theoretically.
