摘要：

A macrocyclic iron(III) 18- azametallacrown- 6 compound, [Fe-6(5-Brashz)(6)(H2O)(6)] center dot 20H(2)O (5-Brashz = N-acetyl-(5-bromosalicylhydrazide)), where the pentadentate ligands bridge the metal ions, was synthesized and characterized. Due to the meridional coordination of the ligand to the metal ion, the ligand is not only bridging the ring metal ions using a hydrazide N-N group, but also enforcing the stereochemistry of the metal ions as a propeller shape with alternating Lambda/Delta configuration. The disc-shaped hexanuclear cluster is about 14.5 angstrom in diameter, 16.8 angstrom in thickness and has a vacant cavity in the center of the cluster.
