Exo-coordination-based supramolecular silver(I) complexes of S2O macrocycles:: Effect of ligand isomerism on the structural diversity

An isomeric series of S2O macrocycles incorporating a xylyl group at the ortho (L-1), meta (L-2), and para. (L-3) positions were employed to examine the influence of the ring rigidity on silver(I) coordination modes in resulting supramolecular complexes (1-3); L-1 and L 3 afforded sandwich (1; Ag:L-1 = 1:2) and infinite 1-D (3) complexes, respectively; otherwise, L-2 gave the 1-D polymer (2a), 2:3 club sandwich (2b), and unique 2:4 bridged dinuclear complex (2c) complexes, in which their topologies vary with the solvent used.
