Extreme macrocyclization! An ultramacrocyclic structure with 238 non‐hydrogen atoms in its backbone is obtained quantitatively through the reversible catenation of a double‐loop compound that contains Pd II ‐clipped coordination rings at both ends (see structure). The Pd II ring can be regarded as a nanoscale reaction center that is available for connecting nanoscopic components without high entropy costs.
