Reactions of [Fe3Cp2(CO)3(μ-CO)(μ3-CO)(μ3-CF3C2CF3)] with diphosphines: X-ray structure of a complex in which two tri-iron clusters are linked only by Ph2PCH2CH2PPh2

Reactions of the trinuclear iron cluster [Fe3Cp2(CO)3(μ-CO)(μ3-CO)(μ3-CF3C2CF3)] (1) with diphosphines yield mainly the hexanuclear compound in which two tri-iron cluster units are linked by the diphosphine.
