Abstract
Two thiaoxa-macrocycles (L1: S3O2 and L2: S2O3) with a dibenzo-subunit were synthesised and structurally characterised by X-ray analysis. Reactions of L1 and L2 with silver(I) salts (NO3− and PF6−) afforded the respective ligand- and/or anion-directed complexes 1–3 with different topologies; tetranuclear sandwich [Ag4(L1)2(NO3)4] (1), cyclic tetramer [Ag4(L1)4](PF6)4 (2) and poly(bicyclic dimer) [Ag(L2)NO3]n (3). The formation of such supramolecular complexes is discussed in terms of donor or anion effect.
