Abstract:

A novel macrocyclic hexanuclear iron(III) 18-azametallacrown-6 compound, [Fe6(C9H7N2O3) 6(CH3OH)6]·8CH3OH· 2H2O, has been prepared using a trianionic pentadentate ligand N-acetylsalicylhydrazide (ashz3-) and characterized by X-ray diffraction. Due to the meridional coordination of the ligand to the Fe3+ ion, the ligand enforces the stereochemistry of the Fe3+ ions as a propeller configuration with alternating Λ/Δ forms. The disc-shaped hexanuclear ring shows about 6.20 Å in diameter at entrance, about 9.31 Å at its largest diameter at the center of the cavity, respectively. There are many kinds of intramolecular and intermolecular hydrogen bonds in the title compound. The O-H···O hydrogen bond distances range from 2.609(5)-2.901(5) Å. The magnetic susceptibility (4-275K) study indicates antiferromagnetic exchange interactions between the adjacent Fe3+ ions around the ring. © 2002 Elsevier Science B.V. All rights reserved.
