Abstract:
The survey of the shortest contacts in structures deposited in the Cambridge Structural Database shows that chalcogen...halogen, halogen...halogen and chalcogen...chalcogen interactions can compete as cohesion forces in molecular crystals. The smallest parameter δ (defined as the interatomic distance minus the sum of relevant van der Waals radii) for Ch...X contacts between chalcogens (Ch: S, Se) and halogens (X: F, Cl, Br, I) is present only in 0.86% out of 30 766 deposited structures containing these atoms. Thus, in less than 1% of these structures can the Ch...X forces be considered as the

Abstract:
It is widely accepted that the sharing of electrons constitutes a bond. Conversely, molecular interactions that do not involve electron transfer, such as van der Waals forces and electrostatics are defined as "non-bonding" or "non-covalent" interactions. More recently computational and experimental observations have shown situations where the division between "bonding" and "non-bonding" interactions is blurred. One such class of interactions are known as σ-hole interactions. Chapter 1 provides a literature review of investigations into the nature of σ-hole interactions, highlighting the indivi

The heterocycles with tellurium undergo reversible oxidation but those with sulfur or selenium are irreversibly oxidized. The ionization energies of these mesocyclic chalcogenoethers were determined by photoelectron spectroscopy. These lowest ionization energies reflect substantial (0.53-0.75 eV) orbit

Abstract:
Chalcogen-containing materials are an area of increasing interest for spintronic applications. The synthesis, structures and reactivity of these novel compounds are normally studied by solution-state nuclear magnetic resonance (NMR) spectroscopy, density functional theory (DFT) calculations and single-crystal X-ray diffraction. In this thesis, a range of chalcogen-containing heterocycles has been explored, focussing on the solid-state nature and exploring the bulk samples. Therefore, all materials were studied by powder X-ray diffraction and solid-state NMR, in addition to conventional solutio

Abstract:
Noncovalent interactions are vital for functioning of biological systems. For instance, they facilitate DNA base pairing or protein folding. Recently, in addition to classical noncovalent interactions such as hydrogen bond, nonclassical noncovalent interactions have been discovered. An example of these interactions is halogen bond belonging to the class of σ-hole interactions, the knowledge of which is already being useful for medical compound design. The aim of this work is to find out if the chalcogen bond, also a σ-hole interaction, plays a role in the binding of existing viral inhibitors,
