High-Yield Syntheses and Reactivity Studies of Fe10“Ferric Wheels”: Structural, Magnetic, and Computational Characterization of a Star-Shaped Fe8Complex

“…This is a reflection of the diverse areas to which such chemistry is relevant, from magnetic materials to mineralogy and biology. Molecular oxide-bridged iron(III) clusters with structural or other relevance to minerals such as hematite or ferrihydrite, the iron-oxo-hydroxo core of the iron storage protein ferritin, and biomineralization in general are some of the areas of interest in high-nuclearity Fe chemistry. Smaller nuclearity molecules are also of biological interest, such as those containing the [Fe 2 (μ-O)(O 2 CR) 2 ] 2+ core of the oxygen carrier protein hemerythrin and the related cores in other dinuclear Fe proteins such as ribonucleotide reductases, purple acid phosphatases, and methane monooxygenases …”

Methanolysis and Phenolysis Routes to Fe6, Fe8, and Fe10 Complexes and Their Magnetic Properties: A New Type of Fe8 Ferric Wheel

“…Iron plays an important role in diverse areas of nature, from mineralogy to biology. Its most common oxidation state is 3+, which is found in oxide-based minerals such as hematite or ferrihydrite, 11 as well as in a number of biological systems. Of particular interest is the biomineralization of the element and its deposition into iron storage proteins.…”

“…In this way, [Fe 4 O 2 (O 2 CPh) 8 -(py) 2 ] was converted with Al(OR) 3 (R ) Pr i , Bu) to the hexanuclear product [Fe 6 O 2 (OR) 8 (O 2 CPh) 6 ]. 11 A related method uses the relative acidity of alcohols to transform iron(III) salts or (more rarely) preformed Fe x clusters into alkoxide-containing complexes in the absence of more aggressive alkoxide sources. These controlled alcoholysis reactions take place under milder conditions than the aforementioned metathesis reactions.…”

“…Very recently, a similar reaction was reported that employed aluminum alkoxides in a reaction with a preformed cluster rather than a simple iron salt. In this way, [Fe 4 O 2 (O 2 CPh) 8 (py) 2 ] was converted with Al(OR) 3 (R = Pr i , Bu) to the hexanuclear product [Fe 6 O 2 (OR) 8 (O 2 CPh) 6 ] …”
