Crystal structures of the heavier main group elements in low oxidation states have been evaluated for the presence of supramolecular element(lp)center dot center dot center dot pi(arene) interactions that are structure-directing. It is revealed that when present, these interactions lead to zero-dimensional, binuclear aggregates but higher-nuclearity species are sometimes observed, with one-dimensional supramolecular chains of varying topology being prominent. By contrast, two-dimensional aggregation based on element(lp)center dot center dot center dot pi(arene) interactions are rare. In summary, interactions of main group metal lone-pairs with aromatic rings are revealed as synthons capable of assembling molecules into supramolecular aggregates.
