Supramolecular aggregation patterns based on the bio-inspired Se(lone pair)⋯π(aryl) synthon

Consistent with macromolecular structures, Se(lone pair)⋯π(aryl) interactions are found in the crystal structures of molecular compounds. Supramolecular aggregation patterns based solely on these types of interactions were usually zero- or one-dimensional with a smaller number of examples of two- and three-dimensional architectures. The analysis proves that Se(lone pair)⋯π(aryl) interactions function as supramolecular synthons in the structural chemistry of selenium compounds.
