Abstract

The aerobic reaction of the Schiff-base ligand N-(benzimidazol-2-yl)salicylaldimine (Hbisi) with iron(II) perchlorate in methanol leads to the formation of the remarkable coordination compound [Fe₄(μ₄-O)(μ-MeO)₄(bisi)₄](ClO₄)₂·4MeOH (1), whose single-crystal X-ray structure reveals the presence of a discrete Fe^III₄(μ₄-O) core. Magnetic and Mössbauer studies both show that the exchange interaction within the square tetranuclear iron(III) unit is dominated by the central bridging μ₄-oxido ligand, the involvement of the μ-methoxido bridges being negligible.
