✦ Synopsis

New macrocyclic dinucleating ligands have been easily synthesized by Schiff-base condensation reaction with the appropriate aldehyde and amine using the boric ion template method. The ligands have two N2O2 metal-binding sites which are doubly linked to each other with methylene spacers. The ligands chelate with Co 2+ , Cu 2+ and Ni 2+ to form dimetallic compounds in high yields.
