Chemical Reactivity Perspective into the Group 2B Metals Halides

Area of Science:

• Computational chemistry
• Theoretical chemistry
• Quantum chemistry

Background:

• Conceptual density functional theory (DFT) provides insights into chemical interactions.
• Understanding interactions between metal halide monomers is crucial for simulations.
• Group 2B metal halides (Zn, Cd, Hg with F, Cl, Br, I) are relevant in various chemical contexts.

Purpose of the Study:

• To investigate chemical reactivity descriptors for Group 2B metal halide monomers and dimers.
• To correlate reactivity descriptors with dimerization energies, considering relativistic effects.
• To systematically analyze relativistic effects on chemical reactivity in these compounds.

Main Methods:

• Utilized density functional theory (DFT) for calculations.
• Employed the effective core potential (ECP) approach to include relativistic effects.
• Calculated global and local chemical reactivity descriptors.
• Analyzed correlations between descriptors and dimerization energies.

Main Results:

• Established correlations between global/local reactivity descriptors and dimerization energies.
• Demonstrated the influence of relativistic effects on chemical reactivity.
• Identified steric effects as a significant factor causing deviations from established chemical reactivity principles.
• Showed that steric effects impact local softness descriptors.

Conclusions:

• The study provides a systematic investigation of Group 2B metal halides, combining relativistic effects and reactivity descriptors.
• Steric effects play a crucial role in the reactivity of these compounds, influencing descriptors like local softness.
• Findings contribute to a better understanding of metal halide interactions for potential applications in simulations.
