The P and M enantiomers of the octanuclear [Fe 8 (μ 4 ‐O) 4 (μ‐4‐Cl‐pz) 12 Cl 4 ] complex, having T symmetry, were resolved by temporary substitution of chloride ligands by racemic 4‐ s Bu‐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 determination. This work constitutes a rare example of enantiomeric recognition resulting in spontaneous resolution upon crystallization.
