Enough mechanical stiffness that the metal centers can no longer racemize is provided by the connection of four labile metal centers (Al III , Ga III , In III , Fe III ) and six achiral bis‐catecholate ligands in a rigid tetrahedral assembly (see picture). The resolution and unprecedented kinetic stability of such a chiral supramolecular assembly is reported here for the first time.
