A Hexanuclear Iron(III) Carboxylate with an [Fe₆(μ₃‐O)₃(μ₂‐OH)]¹¹⁺ Core as an Efficient Catalyst for Cycloalkane Oxidation

Six of one: A hexanuclear iron p-nitrobenzoate compound (see structure; green Fe, red O, blue N, gray C), a novel type of iron cluster was prepared and characterized. The complex has an [Fe6(μ3-O)3(μ2-OH)]11+ core and shows a remarkable catalytic activity in the oxidation of cyclohexane.
