Basic applications of the information entropy concept to chemical objects are reviewed.
These applications deal with quantifying chemical and electronic structures of molecules …

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 …

The common structural features of optically active compounds, known in 1874, led van't Hoff
and, independently, Le Bel to the conclusion that tetracoordinate carbon compounds of type …

Carbon centres in typical organic molecules have a coordination number that can reach a
maximum of four, in which case the bonded atoms are situated at the vertices of a …

In 1995, the synthesis, properties and remarkable hydroboration activity of bis-
pentafluorophenyl borane was first reported. Its reactivity stems from the ready accessibility …

We summarize our contributions on the quest of new planar tetracoordinate carbon entities
(new carbon molecules with exotic chemical structures and strange bonding schemes). We …

In this feature article, an overview of the chemistry of pyramidanes, as a novel class of main
group element clusters, is given. A general introduction sets the scene, briefly presenting the …

We report evidence for the first global-minimum structure having a planar pentacoordinate
carbon. High-level ab initio computations and quantum molecular dynamics simulations at …

Boroles and borapyramidanes are classical and nonclassical constitutional isomers,
respectively. It is here shown that they can indeed be interconverted. Treatment of the bis …

Using quantum-chemical calculations and reduced dimensionality, we show that the “post-
anti-van't Hoff-Le Bel” motif of germanium can be stabilized in a novel two-dimensional (2D) …
