An overview of intermolecular interactions occurring between each of selenium and tellurium centers, in both the +II and +IV oxidation states (i.e. with two and one available lone pairs) with arene rings, that is M(lone pair) ⋯ π(arene) interactions, in their crystal structures is presented. These M(lone pair) ⋯ π(arene) interactions are proven to be important in stabilizing supramolecular architectures in their respective solid-state structures. Thus, when operating in isolation of other intermolecular forms of association, for example hydrogen bonding and secondary interactions, M(lone pair) ⋯ π(arene) interactions usually lead to either zero- and one-dimensional supramolecular aggregation patterns often sustained by one donor and one acceptor M(lone pair) ⋯ π(arene) interaction per molecule. Intriguingly, examples are also presented for two- and even three-dimensional architectures stabilized by this supramolecular synthon alone, indicating that some molecules, often with higher nuclearity, can form multiple M(lone pair) ⋯ π(arene) interactions. Rarely, when the selenium or tellurium center is in the +II oxidation state does the element form two such interactions. In conclusion, it is suggested that any complete analysis of any selenium- or tellurium-containing crystal structure should include an evaluation for M(lone pair) ⋯ π(arene) interactions.
