Since the prediction of the existence of metallabenzenes in 1979, metallaaromatic chemistry
has developed rapidly, due to its importance in both experimental and theoretical fields …

The idea of planar tetracoordinate carbon (ptC) was considered implausible for a hundred
years after 1874. Examples of ptC were then predicted computationally and realized …

In 1972, within a study of the structure-dependency of total π π-electron energy (EE), it was
shown that EE depends on the sum of squares of the vertex degrees of the molecular graph …

Metal–metal bonding is a widely studied area of chemistry,–, and has become a mature field
spanning numerous d transition metal and main group complexes,,–. By contrast, actinide …

The occurrence of aromaticity in organic molecules is widely accepted, but its occurrence in
purely metallic systems is less widespread. Molecules comprising only metal atoms (M) are …

Increasing interest in the computational modeling of actinide compounds creates the need
for alternative choices when in comes to fine tuning the computational methodology in order …

Metallaaromatics can be broadly defined as aromatic compounds in which one of the ring
atoms is a transition metal. The metallabenzenes are one important class of these …

The usefulness of aromaticity/antiaromaticity concepts to foresee structural stability patterns
and salient features of the electronic structure of small inorganic and all-metal rings has …

We present new insight into the nature of aromaticity in metal clusters. We give
computational arguments in favor of using the ring-current model over local indices, such as …

In the last decade, the study of aromaticity has experienced enormous progress. The new
discoveries, which include species such as the metallabenzenes, heterometallabenzenes …
