Synthesis and magnetic properties of wheel-shaped [Mn-12] and [Fe-6] complexes
The reactions of the ligands N-methyldiethanol amine and N-ethyldiethanol amine (abbreviated H(2)mdea and H(2)edea, respectively) with [Mn12O12(O2CCH3)(16)(H2O)(4)] yield novel dodecanuclear wheel-shaped products. The capability of the ligands H2mdea and H2edea to support wheel structures in metals other than Mn is demonstrated with the crystal structure of a new hexanuclear ferric wheel.
