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 [Fe-4(mu(4)-O)(mu-MeO)(4)(bisi)(4)]-(ClO4)(2)center dot 4MeOH (1), whose single-crystal X-ray structure reveals the presence of a discrete Fe-4(III)(mu(4)-O) core. Magnetic and Mossbauer studies both show that the exchange interaction within the square tetranuclear iron(III) unit is dominated by the central bridging mu(4)-oxido ligand, the involvement of the mu-methoxido bridges being negligible.
