Although being composed of high valent ions, the crystal structures of four new supramolecular intercluster compounds, presented in this article, display a major contribution of short-range intermolecular interactions, i.e., aromatic pi-pi interactions. These structure-directing forces has lead to the formation of an distorted NaCl-type packing in [Ag(5)(2,2'-bipyridine)(4)(C CtBu)(2)][PW(12)O(40)] and [Ag(5)(2,2'-bipyridine)(4)(C CtBu)(2)][PMo(12)O(40)], and a CsCl-type packing in [Ag(8)(2,2'-bipyridine)(6)(C CtBu)(4)(C(3)H(7)NO)(2)][SiW(12)O(40)] and [Ag(8)(2,2'-bipyridine)(6)(C CtBu)(4)(C(3)H(7)NO)(2)][SiMo(12)O(40)].
