A palladium‐conjoined molecular square obtained by using a pyrene‐bis‐imidazolylidene ligand is described. This "three‐dimensional" metallo‐polygon is suitable for the encapsulation of C60 and C70. The X‐ray diffraction structures of the empty and complexed cage with both fullerenes are described. The encapsulation of the fullerenes produces perturbations in the structural parameters of the metallo‐square, showing that it can adapt the shape of its cavity to the size of each fullerene.
