The P and M enantiomers of the octanuclear [Fe8(μ4‐O)4(μ‐4‐Cl‐pz)12Cl4] complex, having T symmetry, were resolved by temporary substitution of chloride ligands by racemic 4‐sBu‐phenolates and subsequent crystallization, where the (S)‐ and (R)‐phenolates coordinate selectively to the M and P complexes, respectively. The complexes were characterized by circular dichroism analysis and X‐ray structure...
One‐electron reduction of a pyrazolate‐bridged triangular Fe3(μ3‐O) core induces a cascade wherein all three metal centers switch from high‐spin Fe3+ to low‐spin Fe2.66+. This hypothesis is supported by spectroscopic data (1H‐NMR, UV‐vis‐NIR, infra‐red, 57Fe‐Mössbauer, EPR), X‐ray crystallographic characterization of the cluster in both oxidation states and also density functional theory. The reduction...
