Construction of the Multidecker Anthracene-Silver(l) System by Intramolecular Pi-Pi Interactions

As a continuation of the study on the construction of the multidecker aromatic compounds with Pi-Pi interactions, the anthracene derivatives 9,10-dimethylanthracene (dman), 9,10-diphenylanthracene (dpan), and 7,12-dimethylbenz[a]anthracene (dmban) have been studied toward complexation with the silver(l) ion. The crystal structures of [Ag(dman)o.5(p-xylene)(CIO4)],[Ag2(dpan)0.5(C6H6(CF3FaSO3)2], and [Ag2(dmban)2(CiO4)2[p-xylene), together with the metal-free ligand dpan, have been determined by single-crystal X-ray diffraction. These Pi-electron-rich aromatic compounds are found to have great promise as an approach to the effective self-assembly of high nuclearity in a multilayer fashion.
