Journal ArticleDOI
The nature of the supramolecular association of 1,2,5-chalcogenadiazoles.
TL;DR: In this paper, the relativistic density functional theory was applied to the 1,2,5-chalcogenadiazoles and showed that tellurium derivatives possess the strongest association energies; these are so large that the binding strength is comparable to some hydrogen bonds.
Journal ArticleDOI
A survey of tellurium-centered secondary-bonding supramolecular synthons
TL;DR: The structural motifs assembled in these systems fall within eight general categories, from single to multiple-bonded supramolecular synthons as mentioned in this paper, and the overall structures assembled by the most important tellurium-based SISs and prospects for their application in crystal engineering are discussed.
Journal ArticleDOI
Supramolecular macrocycles reversibly assembled by Te … O chalcogen bonding

TL;DR: Oligomeric aggregates of heterocycles that are linked by chalcogen-centered interactions and behave as genuine macrocyclic species are presented.
Journal ArticleDOI
Recent developments in the coordination chemistry of bis(imino)acenaphthene (BIAN) ligands with s- and p-block elements.
TL;DR: The unique stereoelectronic properties of the BIAN ligand class are beginning to be appreciated and exploited for some fascinating new developments in synthetic, structural and catalytic s- and p-block chemistry.
Journal ArticleDOI
The effect of steric hindrance on the association of telluradiazoles through Te-N secondary bonding interactions
TL;DR: In this article, DFT calculations were used to compare the magnitude of steric repulsion to the strength of secondary bonding interactions (SBIs) in the (Te−N)2 supramolecular synthon to explain or predict the supramerolecular structures assembled by two derivatives of the 1,2,5-telluradiazole ring.
