As a continuation of the study on the construction of the multidecker aromatic compounds with π−π 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(I) ion. The crystal structures of [Ag(dman)0.5(p-xylene)(ClO4)], [Ag2(dpan)0.5(C6H6)0.5(CF3SO3)2], and [Ag2(dmban)2(ClO4)2](p-xylene), together with the metal-free ligand dpan, have been determined by single-crystal X-ray diffraction. These π-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.
