Supramolecular 3D Polymers Created via Chalcogen Bonding Using Benzotellurazoles as Planar Recognition Units.

ABSTRACT: In addition to hydrogen and halogen bonds, chalcogen bonds (ChBs) are gaining significance in the domain of crystal engineering. Nitrogen-containing tellurium compounds are well-suited for this purpose, as they form a variety of solid-state structures through ChBs. Despite prior studies addressing substituent effects in benzotellurazoles, the influence of fluorine atoms on the benzene backbone of 1,3-benzotellurazoles remains to be investigated in the context of solid-state arrangement. Here, we demonstrate that the incorporation of fluorine atoms can impact the nature and quantity of ChBs in the solid state. The electron-withdrawing properties of the introduced substituents result in alterations to the ChB donor (Te) and acceptor (N) properties, leading to a preferential interaction with
