Conspectus The distribution of the electron density around covalently bonded atoms is
anisotropic, and this determines the presence, on atoms surface, of areas of higher and …

The halogen bond occurs when there is evidence of a net attractive interaction between an
electrophilic region associated with a halogen atom in a molecular entity and a nucleophilic …

Halogen bonding, the noncovalent interaction based on electrophilic halogen substituents,
features very interesting properties, as illustrated by numerous applications continuously …

Supramolecular chemistry is “the chemistry of the intermolecular bond, covering the
structures and functions of the entities formed by association of two or more chemical …

The study of the complexation of anions, from its beginnings in the late 1960s and 1970s,(1-
3) has moved on from being an area solely of academic interest to a fundamental pillar of …

In the field of noncovalent interactions a new paradigm has recently become popular. It
stems from the analysis of molecular electrostatic potentials and introduces a label, which …

The σ-hole and π-hole are the regions with positive surface electrostatic potential on the
molecule entity; the former specifically refers to the positive region of a molecular entity …

How do molecules aggregate in solution, and how do these aggregates consolidate
themselves in crystals? What is the relationship between the structure of a molecule and the …

The distribution of distances from atoms of a particular element E to a probe atom X (oxygen
in most cases), both bonded and intermolecular non-bonded contacts, has been analyzed …

Conspectus The halogen bond is an attractive interaction in which an electrophilic halogen
atom approaches a negatively polarized species. Short halogen atom contacts in crystals …
