A tetrel bond can be defined as an interaction between any electron donating moiety and a
group 14 element acting as Lewis acid. Experimental and theoretical research on this …

Following the systematic nomenclature recommended by the IUPAC for other π, σ-hole
interactions, a nobel gas (or aerogen) bond (NgB) is defined as the attractive interaction …

Structure–property relationships are the key to modern crystal engineering, and for
molecular crystals this requires both a thorough understanding of intermolecular …

A set of 35 representative neutral and charged tetrel complexes was investigated with the
objective of finding the factors that influence the strength of tetrel bonding involving single …

The fundamental underpinnings of noncovalent bonds are presented, focusing on the σ-hole
interactions that are closely related to the H-bond. Different means of assessing their …

Over the last years, scientific interest in noncovalent interactions based on the presence of
electron-depleted regions called σ-holes or π-holes has markedly accelerated. Their high …

In addition to the standard halogen bond formed when NH 3 approaches XCN (X= F, Cl, Br,
I) along its molecular axis, a perpendicular approach is also possible, toward a π-hole that is …

The ability of metal clusters involving elements from group 11 (Ag, Cu, Au) to favorably
interact with π systems of different size and electronic nature was evaluated at the PBE0 …

Accompanying the rapidly growing list of σ-hole bonds has come the acknowledgment of
parallel sorts of noncovalent bonds which owe their stability in large part to a deficiency of …

By means of molecular orbital theory and the analysis of charge transfer and electrostatic
forces, we discuss the features of non-covalent hole interactions of the halogen, chalcogen …
