Chalcogen bonds (ChB) are developed as crystal engineering tools . Dicyanoselenadiazole and dicyanotelluradiazole derivatives are promising supramolecular synthons with the ability to form double chalcogen bonds with a wide range of electron donors including halides and oxygen‐ and nitrogen‐containing heterocycles. An extensive 77 Se and 125 Te solid‐state nuclear magnetic resonance spectroscopic investigation of a large series of cocrystals establishes correlations between the NMR parameters of selenium and tellurium and the local ChB geometry.
