Abstract
The structure of the binuclear Cu2+ complexes with the two title ligands are unexpected and completely different from each other, the 14-membered macrocycle giving a true binuclear species with two nearly identical Cu2+–macrocycle units, whereas the 12-membered ligands one Cu2+ through the four nitrogens of the macrocycle and two carboxylates and the other one only through carboxylates with a similar structure to that found in many dicopper(II) tetracarboxylate systems.Keywords
