Binuclear macrocyclic copper(II) complexes as receptors for small bridging ligands: X-ray crystal and molecular structure of a µ-azido complex

Abstract

In two binuclear copper(II) complexes of a 30-membered Schiff's base macrocyclic ligand the macrocycle adopts a folded conformation which allows intramolecular linkage of the metal atoms via small bridging ligand (N₃ ^– or OH^–); the structure of the µ-azido complex has been solved by X-ray analysis.
