The (&mgr;-oxo)diiron(III) complexes of N,N'-bis(2-methyl-2-mercaptopropane)-1,5-diazacyclooctane (H(2)bme-daco) and N,N'-bis(mercaptoethyl)-1,5-diazacyclooctane (H(2)bme-daco) ligands present uncommon examples of well-characterized (&mgr;-oxo)diiron(III) species in the presence of sulfur donors. Whereas the reaction of molecular oxygen with a solution of diiron(II) complex, [(bme-daco)Fe](2), affords slow formation of
