A new cationic tetranuclear copper(II) complex self‐assembles from one 1,3‐phenylenebis(oxamato) (mpba) bridging ligand and four Cu II ions partially blocked with N , N , N′ , N′ ‐tetramethylethylenediamine (tmen) terminal ligands. In the solid state, two of these tetracopper(II) oxamato complexes of bowl‐like shape and helical conformation then serve as a building block for the generation of either hetero‐ ( MP ) or homochiral ( MM / PP ) dimeric capsules depending on the nature of the encapsulated anion guest, perchlorate or hexafluorophosphate. The overall magnetic behaviour of these metallosupramolecular capsules does not depend on the nature of the encapsulated anion guest, but it is consistent with the dimer‐of‐dimer structure of the tetracopper(II) cation host, where the interdimer magnetic coupling through the meta ‐phenylenediamidate bridge is negligibly smallrelative to the reasonably strong intradimer one across the oxamato bridge.(© Wiley‐VCH Verlag GmbH & Co.
