(2,2-Dichloro­vinyl)ferrocene

The title compound, [Fe(C5H5)(C7H5Cl2)], represents a versatile building block for the preparation of [pi]-conjugated redox-active compounds or polymetallic organometallic systems due to the presence of the electrochemically active ferrocenyl unit. It is therefore a potential starting material for the preperation of the corresponding alkyne. In the crystal, the alkenyl unit and the cyclo­penta­dienide ring are almost parallel, with an angle between the best planes of only 10.6 (4)°.
