A cyclic tetrapeptide <b>L</b> comprising two l-proline and two 3-amino-5-(pyridin-4-yl)benzoic acid subunits assembles into a dimetallic metallamacrocycle <b>Pd</b><sub><b>2</b></sub><b>L</b><sub><b>2</b></sub> and a trimetallic coordination cage <b>Pd</b><sub><b>3</b></sub><b>L</b><sub><b>6</b></sub> in the presence of suitable palladium(II) precursors. <b>Pd</b><sub><b>2</b></sub><b>L</b><sub><b>2</b></sub> recognizes organic anions in aqueous media, forming a particularly stable complex with sodium 2,6-naphthalenedisulfonate, in which two dianionic guest molecules reside in the cavity surrounded by the cyclopeptide ligands.
