Abstract: Abstract Reaction of 2,5‐diformylfuran with 3‐oxapentane‐1,5‐diamine in the presence of the perchlorate salts of Ca, Sr, or Ba leads to the isolation of the macrocyclic complexes (I) or (II) (detailed structures unknown) depending on the metal ion and the choice of solvent (MeCN or EtOH).
