Neutral noble gas compounds exhibiting a Xe–Xe bond: structure, stability and bonding situation
文献信息
Israel Fernández, Gernot Frenking
The structure and stability towards decomposition of eight novel noble gas compounds having a Xe–Xe bond, which have not been experimentally observed so far, have been studied computationally. In addition, the nature of the Xe–Xe interaction has been analysed by a combination of the most popular methods to study the bonding situation of molecules, i.e. Natural Bond Orbital, Atom in Molecules and Energy Decomposition Analysis methods. Two related series of compounds have been considered: HXeXeX (X = F to I) and RXeXeR′ (R = halogen atom). Our calculations indicate that the replacement of the fluorine atom by a heavier group 17 congener in the HXeXeX series leads to a less stable compound, thus making more difficult its experimental observation. The same effect occurs in the RXeXeR′ series, but these species are more kinetically protected against the decomposition reaction and therefore, their experimental detection is more likely.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
