Metalloreceptors 1a and 1b were synthesized by palladation of 42‐ and 54‐membered crown ethers that have two SCS‐pincer ligand moieties. The X‐ray crystallographic analysis reveals that the metalloreceptor 1b has a folded structure in which the two pincer‐Pd moieties are stacked in a parallel manner. The metalloreceptor 1b recognizes the aromatic bidentate guests 4,4′‐bipyridine, pyrazine, and pyrimidine and binds to them in a bridging fashion to form the corresponding bimacrocyclic 1:1 complex.
