在S(2)O(3)大环与AgPF(6)和AgClO(4)的反应中分别得到阴离子控制的内环和外环配合物。在大环腔内(PF（6)(-)）或外(ClO（4)(-)）提供Ag离子位置的两种配位模式可以用阴离子对金属阳离子的配位能力来解释。此外，每个Ag中心通过规则配位键或π配位连接两个配体，形成环状二聚体型产物。并对溶液中的络合体系进行了核磁共振滴定。
Anion-controlled endo- and exocyclic complexes were afforded in the reactions of an S(2)O(3) macrocycle with AgPF(6) and AgClO(4), respectively. The two coordination modes that provide the Ag ion position inside (by PF(6)(-)) or outside (by ClO(4)(-)) 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.
