Abstract

Abstract: The self‐assembly of 2, 5‐diformylpyrrole, tris(2‐aminoethyl)amine, and silver(I) yielded, depending on the size and basicity of the anion, new cascade complexes or plenates, that is, cryptates incorporating Ag n n + clusters. The nature of the product was counterion‐dependent, and its formation was either driven by cascade anion binding or by argentophilic interactions stabilizing the cluster within the cavity. The reaction of plenates with tetrabutylammonium halides resulted in the protonation‐coupled replacement of the Ag3 3+ with anion(s), yielding cascade cryptates. Abstract : Cages full of silver : The self‐assembly of diformylpyrrole, tren amine, and silver(I) halides yielded cascade complexes incorporating the [Ag2 F] + unit or the Ag2 Cl2 ion pair. Exploitation of silver(I) triflate, incorporating a bulky anion, resulted in the formation of plenates, that is, cryptates incorporating Ag n n + clusters. The latter transformed into cascade cryptates upon reaction with tetrabutylammonium halides.
