Abstract: The self assembly of AgX with the sulfur-containing multidentate ligand alpha,alpha'-bis(8-thioquinoline)-m-xylene (m-XYTQ) affords two isomorphous complexes [Ag(m-XYTQ)](n)X-n (X = ClO4 1; X = BF4 2). Single crystal X-ray analyses revealed the complexes to contain linear cationic chains of [Ag(m-XYTQ)](n) (n+) in helical arrangement and the anions are discrete. Intramolecular pi(...)pi stackings pack the asymmetric units [Ag(w-XYTQ)] in shelves-like arrays while interchain pi(...)pi interactions between racemic chains constructed the 2D network, The key to helix formation is the folding at the sulfur sites of the spacer xylylene in the ligand, The complexes were also characterized by H-1 NMR and IR.
