Abstract

Reactions of a hexadentate ligand N,N,N’,N’-tetrakis(2-hydroxyethyl)ethylenediamine (H₄edte) with different iron(III) salts in different solvents yielded three new twisted-saddle Fe₁₂ clusters with adamantane-like [Fe₄O₆] inner core. Preliminary magnetic studies show that strong intracluster anti-ferromagnetic interaction exists in both 1 and 3, generating the S_T = 0 spin ground state.
