Beryllium bonding with noble gas atoms.

Area of Science:

• Quantum Chemistry
• Computational Chemistry
• Materials Science

Background:

• Beryllium clusters are of interest due to their unique electronic properties.
• Understanding interactions between small metal clusters and noble gases is crucial for various applications.

Purpose of the Study:

• Investigate the bonding nature between a neutral Be3 ring and noble gas atoms.
• Characterize the electronic structure and interaction types within these complexes.

Main Methods:

• Quantum chemical calculations at various computational levels.
• Natural Bond Orbital (NBO) and Quantum Theory of Atoms in Molecules (QTAIM) analyses.
• Electron Localization Function (ELF), Symmetry Adapted Perturbation Theory (SAPT), and Molecular Electrostatic Potential (MEP) surface analysis.

Main Results:

• Be3 moiety exhibits strong Be-Be chemical bonds with a dissociation energy of ~125 kJ/mol.
• Be3 ring interacts with noble gases through non-covalent interactions.
• Binding energy with noble gases increases with atomic number; dispersion is the primary stabilizing factor.

Conclusions:

• The Be3 ring is a stable unit capable of forming non-covalent complexes with noble gases.
• Dispersion forces significantly contribute to the stability of Be3-noble gas complexes.
• These findings offer insights into the chemistry of small metal clusters and noble gas interactions.
