Anion-controlled endo- and exocyclic complexes were afforded in the reactions of an S2O3 macrocycle with AgPF6 and AgClO4, respectively. The two coordination modes that provide the Ag ion position inside (by PF6-) or outside (by ClO4-) the macrocyclic cavity are explained by the anion-coordination ability toward the metal cation. Furthermore, each Ag center bridges two ligands via a regular coordinative bond or by pi coordination, forming a cyclic dimeric-type product. NMR titrations of the complex system in solution were also carried out.

Cu4I4-cubane linked 2Dcoordinationpolymer [(Cu4I4)(L1)2]·CH2Cl2}n (5), one-dimensional (1D) tubular coordinationpolymer [(Cu4I4)(L2)2]·0.8CH2Cl2·0.2CH3CN}n (6), Cu2I2-rhomboid linked 2Dcoordinationpolymer [(Cu2I2)(L3)2]n (7), and 2Dcoordinationpolymer [(Cu2I2)(L4)2]n (8), respectively. The reactions of the above ligands with mercury(II) salts (I– and SCN–) gave a cyclic dimer complex [Hg2(L3)2I4]

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.
