Gold⋯π aryl interactions as supramolecular synthons†
Abstract
Au⋯π interactions whereby the electron-rich π-system of C6-aromatic rings interact with gold are shown to exist in the crystal structures of both gold(I) and gold(III) complexes, and have been revealed to occur between neutral/neutral, cationic/cationic, and cationic/anionic systems. Supramolecular aggregation facilitated by Au⋯π interactions leads to the formation of 0-dimensional aggregates, e.g. arising from an interaction between a gold complex and a
