Diiron propanedithiolate hexacarbonyl is the
organoiron complex Organoiron chemistry is the chemistry of iron compounds containing a carbon-to-iron chemical bond. Organoiron compounds are relevant in organic synthesis as reagents such as iron pentacarbonyl, diiron nonacarbonyl and disodium tetracarbonylferrate. ...
with the formula Fe2(S2C3H6)(CO)6. It is a red diamagnetic solid. It adopts a symmetrical structure with six terminal CO ligands. The complex is a precursor to hydrogenase mimics. It is prepared by the reaction of
1,3-propanedithiol 1,3-Propanedithiol is the chemical compound with the formula HSCH2CH2CH2SH. This dithiol is a useful reagent in organic synthesis. This liquid, which is readily available commercially, has an intense stench. Use in organic synthesis 1,3-Propan ...

triiron dodecarbonyl Triiron dodecarbonyl is the organoiron compound with the formula Fe3(CO)12. It is a dark green solid that sublimes under vacuum. It is soluble in nonpolar organic solvents to give intensely green solutions. Most low-nuclearity clusters are pale ...
: :2 Fe3(CO)12 + 3 C3H6(SH)2 → 3 Fe2(S2C3H6)(CO)6 + 3 H2 + 6 CO In general, the CO ligands can be substituted by
cyanide Cyanide is a naturally occurring, rapidly acting, toxic chemical that can exist in many different forms. In chemistry, a cyanide () is a chemical compound that contains a functional group. This group, known as the cyano group, consists of a ...
, phosphines, isocyanides, N-heterocyclic carbenes, and other donor ligands. Monosubstitution can be achieved through an in situ generation of the acetonitrile complex. Upon irradiation of Fe2(S2C3H6)(CO)6 with ultraviolet (UV) light, CO-photolysis occurs with the transient formation of the unsaturated species followed by the formation of the solvent adduct.Mack, A.
