In this review, we provide a consistent description of noncovalent interactions, covering most
groups of the Periodic Table. Different types of bonds are discussed using their trivial …

The chalcogen bond (ChB) is defined as a noncovalent interaction between the electron
density deficient region (so-called as σ or π hole) of a covalently bonded chalcogen atom …

This review considers noncovalent bonds between divalent chalcogen centers. In the first
part we present X-ray data taken from the solid state structures of dimethyl-and diphenyl …

The terms tetrel bond, pnictogen bond and chalcogen bond were coined recently to describe
non-covalent interactions involving group 14, 15 and 16 atoms, respectively, acting as the …

Tautomerism, a particular case of isomerism, plays an important role in modern organic
chemistry, biochemistry, medicinal chemistry, pharmacology, molecular biology, and life …

Weak nonbonded interactions between a divalent sulfur (S) atom and a main-chain carbonyl
oxygen (O) atom have recently been characterized in proteins. However, they have shown …

In the last decade, experiment and theory have expanded our vision of non‐covalent
interactions (NCIs), shifting the focus from the conventional hydrogen bond to new bridging …

To understand the intermolecular interactions between chalcogen centers (O, S, Se, Te),
quantum chemical calculations on model systems were carried out. These model systems …

This article reviews the history and the current state of knowledge concerning the ability of
the heavy chalcogen atoms S and Se, and to some extent Te, to participate in a H-bond as …

To investigate the nature of nonbonded Se⊙⊙⊙ O interactions, three series of 2-
substituted benzeneselenenyl derivatives [2-(CHO) C6H4SeX (1), 2-(CH2OH) C6H4SeX,(2) …
