Summary: The structural analyses of actinide compounds revealed trends in stereochemical preferences, distortion paths, geometrical constraints, and interactions on purportedly vacant coordination sites. The study suggests that actinide chemistry has a higher relative abundance of coordination numbers compared to lanthanides. The detailed shape measures study of coordination polyhedra with coordination numbers between 1 and 6 is based on over 1,800 solid state and gas phase structural data sets.

Summary: The discovery of Single-Molecule Magnets in 1993 revolutionized the field of information storage by shrinking the size of bits to molecular levels. Despite initially operating at temperatures near absolute zero, collaboration between chemists and physicists have led to the development of materials that can operate above liquid nitrogen temperatures. The evolution of SMMs has involved the study of various routes towards high performance materials, with each route essential for understanding the quantum dynamics behind these molecules.

Summary: Hydrophobic magnetic deep eutectic solvents (HMDESs), consisting of a hydrogen bond acceptor, hydrogen bond donor, and a metal halide salt, have been prepared and studied for their physicochemical properties. The viscosity, magnetic susceptibility, and thermal stability of these solvents can be easily tailored by varying the composition and molar ratio. With their structural tunability, HMDESs show great potential for a wide range of applications.

Summary: This article investigates the degree of interpenetration of van der Waals crusts to better quantify nonbonding contact distances between atoms. The study focuses on the structural trends of intermolecular contacts between tetramethylammonium cation (TMA) and halogen atoms. Computational analysis of model X⋅⋅⋅TMA ion pairs (X = F, Cl, Br, I, Au) reveals two energy minima, with anions interacting simultaneously with three hydrogen atoms. The results demonstrate significant variation in charge distribution around different atoms and its dependence on the distance to the central N atom.

Summary: The geometry, strength, and physical nature of bonding in halonium cationic compounds have been comprehensively studied through a combined structural and computational analysis. The investigation focused on [D......X......D]+ halonium compounds, where D is a Lewis base and X is Cl, Br, or I. Various factors, including different halogen atoms (X) and nitrogen-donor groups (D) attached to an iodonium cation, were analyzed to understand their influence on the symmetry, strength, and nature of the interaction. The interaction arises from an interplay between electrostatic and orbital contributions, with potential applications in halofunctionalization and supramolecular chemistry.
