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 …

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 …

A covalently-bonded atom typically has a region of lower electronic density, a “σ-hole,” on
the side of the atom opposite to the bond, along its extension. There is frequently a positive …

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 …

Non‐covalent interactions play a crucial role in (supramolecular) chemistry and much of
biology. Supramolecular forces can indeed determine the structure and function of a host …

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 …

A σ-hole bond is a noncovalent interaction between a covalently-bonded atom of Groups IV–
VII and a negative site, eg a lone pair of a Lewis base or an anion. It involves a region of …

Halogen bonding is a noncovalent interaction that is receiving rapidly increasing attention
because of its significance in biological systems and its importance in the design of new …

Halogen bonding is the noncovalent interaction where halogen atoms function as
electrophilic species. The energetic and geometrical features of the interaction are …

The articles published in the tenth anniversary issue of CrystEngComm are reviewed. The
issue highlighted the state-of-the-art of crystal engineering and new trends and developing …
