| Summary: | Crystal structures of the heavier main group elements in low oxidation states have been evaluated for the
presence of supramolecular elementIJlp)⋯π(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 elementIJlp)⋯π(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. |
