Heteroatom-centered diradical (oid) s have been in the focus of molecular main group
chemistry for nearly 30 years. During this time, the diradical concept has evolved and the …

London dispersion, which constitutes the attractive part of the famous van der Waals
potential, has long been underappreciated in molecular chemistry as an important element …

London dispersion (LD) interactions are the main contribution of the attractive part of the van
der Waals potential. Even though LD effects are the driving force for molecular aggregation …

London dispersion forces are the weakest component of Van der Waals interactions. They
arise from attractions between instantaneously induced dipoles on neighbouring atoms …

Covalent bonds share electron pairs between two atoms and make up the skeletons of most
organic compounds in single, double and triple bonds. In contrast, examples of one-electron …

Steric effects in chemistry are a consequence of the space required to accommodate the
atoms and groups within a molecule, and are often thought to be dominated by repulsive …

An update on some recent developments in the bonding of compounds with multiple bonds
between heavier main group elements is the major theme of this review. A brief historical …

Steric congestions has been made solely responsible for the thermodynamic instability of
hexaphenylethane(1)(Scheme 1).[1] Despite many attempts, all synthetic approaches to …

On the basis of the intramolecular" core-shell strategy," we designed dihydropyracylene with
two spiro (dibenzocycloheptatriene) units, for which theoretical calculations predicted a very …

Neutron diffraction of tri (3, 5-tert-butylphenyl) methane at 20 K reveals an intermolecular C–
H··· H–C distance of only 1.566 (5) Å, which is the shortest reported to date. The compound …
