## Abstract The reaction of anhydrous FeCl~2~ with 2‐(4′,4′‐dimethyloxazolin‐2′‐yl)thiophenolate (ox‐phS^–^) afforded mononuclear [Fe(ox‐phS)~2~] (A) and binuclear [{Fe^III^(ox‐phS)}~2~(μ‐S)~2~] (B). In B, iron(III) and S^2–^ resulted from an unexpected redox reaction involving elemental sulfur and
## Abstract Redox cycling of iron is a critical aspect of iron toxicity. Reduction of a low‐molecular‐weight iron(III)‐complex followed by oxidation of the iron(II)‐complex by hydrogen peroxide may yield the reactive hydroxyl radical (OH^.^) or an oxoiron(IV) species (the __Fenton__ reaction). Comp
