Abstract

Six‐membered heterocycles, 1,4‐dithiane and 1,4‐thioxane, were treated with [Fe~2~(CO)~6~(μ‐pdt)] (pdt = propanedithiolate) in order to synthesise [2Fe3S] complexes with well positioned heteroatoms as potential base. Monosubstituted compounds of general formula [Fe~2~(CO)~5~L(μ‐pdt)] (L = 1,4‐dithiane, 1,4‐thioxane) were mainly obtained and characterised by ^1^H NMR, IR, elemental analysis and X‐ray diffraction studies. Electrochemical behaviour of these monosubstituted derivatives was investigated by cyclic voltammetry. An original tetranuclear cluster with a [4Fe8S] core was also isolated as a minor product and structurally characterised.
