摘要：

Slow diffusion of AgX with O(SiMe2(4-py))(2) (L) yields unique molecular rectangles consisting of [Ag(L)](2)X-2 (X- = NO3-, ClO4-, PF6-, and CF3SO3-). For the rectangular system, the transannular argentophilic (Ag-Ag) interaction competes with the interaction between Ag(I) and its anions, while the pi-pi interactions are constantly preserved. The strength of the argentophilic interaction is in the following order: NO3- > ClO4- > PF6- > CF3SO3- and is reversibly stretched via the anion exchange from 3.20(1) to 3.81(1) Angstrom without the destruction of the cyclic skeleton.
