Aromatic Inorganic and Metallic Compounds II
Topic Information
Dear Colleagues,
Following the successful first edition of the Special Issue “Aromatic Inorganic and Metallic Compounds” (https://www.mdpi.com/journal/molecules/special_issues/86884P1B18) in the journal Molecules, we announce with great pleasure the second edition of “Aromatic Inorganic and Metallic Compounds II”, which is expected to be launched across five MDPI journals including Chemistry, Compounds, Inorganics, Molecules and Reactions.
As one of the most important concepts in chemistry, aromaticity was originally used to help understand the relationship between the structure and properties of cyclic π-conjugated molecules. In 1931, Hückel proposed a simple and effective 4n+2 electronic rule to judge the aromaticity of the ground states of ring-like π-conjugated molecules, in which n was the number of delocalized π electrons. Later, 4n electronic antiaromaticity was added to the Hückel rule by Breslow. The connotations and extensions of aromaticity have been evolving in recent years. Aromatic systems are no longer confined to organic hydrocarbons but extend to inorganic and metallic compounds. As supplements to π aromaticity, σ, δ, and φ aromaticity have been found. Aromaticity is responsible not only for the regular shape, extra stability, and low reactivity of compounds but also for their exotic dynamical properties. In addition, the concept of aromaticity extends from planar molecules to three-dimensional species, such as spherical aromaticity and cubic aromaticity.
There are many ways to evaluate the aromaticity of systems, including the molecular orbital (MO) method combined with Hückel's rule; adaptive natural density partitioning (AdNDP); nucleus-independent chemical shifts (NICSs); the anisotropy of the induced current density (AICD); aromatic ring chemical shieldings (ARCS); magnetic susceptibility exaltation; the harmonic oscillator measure of aromaticity (HOMA); bird aromaticity index; harmonic oscillator stabilization energy (HOSE); aromatic stabilization energy (ASE); magnetic resonance energies (MRE); and electron localization function (ELF).
Aromaticity is very important for revealing the structures and properties of novel compounds. The aim of this Topic is to provide a platform to present the latest research results on aromatic inorganic and metallic species.
