Organic frameworks face a trade-off between the framework stability and bond dynamics, which necessitates development of innovative linkages that can generate stable without hindering efficient synthesis. Although iodine(I)-based halogen-bonded organic (XOFs) have been developed, constructing XOFs based on bromine(I) is desirable yet challenging due to high sensitivity species. In this work, we present inaugural construction bromine(I)-bridged two-dimensional (2D) frameworks, XOF(Br)-TPy-BF

In this paper we revisit earlier work relating to monoatomic atoms and ions published by pioneers in the area of electrostatic potentials. We include plots radial distributions potentials for spherically symmetric cations, singly, doubly triply negative anions. For with anisotropy their densities potentials, such as halonium it is shown how molecular surface approach plotting complements that achieved directional distributions.

Abstract Sulfonium, selenonium, telluronium triflates, as well chloronium, bromonium, and iodonium triflates have been examined in the model Schiff condensation chalcogen‐ halogen bond donating organocatalysts, respectively. The kinetic data indicated that catalytic effect of salt is provided via decrease enthalpy activation reaction, whereas – unexpectedly caused by value entropy activation. In addition, it was experimentally shown activity sulfonium selenonium salts significantly lower than chloronium bromonium salts, but latter pair species less stable under reaction conditions former pair.
