摘要
One of the challenges in molecular magnetism is the preparation of molecular clusters that behave as single-molecule magnets (SMMs).([1]) Such behavior, due to the slow relaxation of the magnetization below a given temperature, may open new horizons for one-molecule information storage-even though not above liquid-helium temperature for the time being. The number of polynuclear complexes that behave as SMMs is increasing and examples of V, Mn, Fe, Ni, and Co complexes can be found in the literature.([2]) But to date, SMMs based on iron(III) are still rare.
