Nature of the Te⋯N intramolecular interaction in organotellurium compounds. A theoretical investigation by NBO and AIM methods

► The nature of Te⋯N interaction in organotellurides is studied theoretically. ► The Te⋯N interaction have a dominant covalent character. ► The strength of Te⋯N interaction is mainly influenced by the TeN distance. ► Polar solvent favors the Te⋯N interaction by shortening TeN distance. ► Te⋯N interaction is found to be stronger than the corresponding Se⋯N interaction.
