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: Crystal packing has a strong influence on the spin crossover behavior, and the halogen substituents affect the crystal structure and magnetic behavior. The study of a series of compounds reveals that compounds 1 and 2 are stabilized in the low spin state, while compound 3 shows an abrupt hysteretic spin crossover. It is concluded that the orientation of the 1D pi-pi chains plays a key role in spin crossover behavior.

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.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
