TLDR
In this paper, the intermolecular contacts between chalcogen atoms and cyano lone pairs were found to stabilize the crystalline state by electrostatic interaction, which is one of the sources of the directionality in crystal paccking of organic molecules and causes the formation of various types of inclusion lattices in the charge transfer (CT) crystals of I-3.Abstract:
The intermolecular contacts between chalcogen atoms and cyano lone pairs were found to stabilize the crystalline state by electrostatic interaction. This interaction is one of the sources of the directionality in crystal paccking of organic molecules and causes the formation of various types of inclusion lattices in the charge-transfer (CT) crystals of I-3. By using highly selective formation of CT crystals with substituted aromatic hydrocarbons, particular isomers such as p-xylene or 2,6-dimethylnaphthalene (2,6-DMN) could be separated from the corresponding isomer mixturesread more

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.
