AbstractIn a series of nine silver(I) complexes synthesized with ethynyl-functionalized condensed-ring benzenoid aromatics, the terminal ethynide group is invariably inserted into an argentophilic Agn (n = 4-5) basket, leading to the generation of coordination chains or multinuclear metallocycles via silver-aromatic interaction and strong face-to-face aromatic pep stacking interaction. The coordination preferences of the ethynide ligand with respect to the size of the aromatic nucleus proved to be dominant factors in directing the construction of multi-dimensional organosilver(I) networks, which are consolidated by weak intermolecular interactions in supramolecular assembly.
