. To the best of our knowledge, these are the first examples of iron dicarbonyl complexes with the trimethylaniline ligand to be reported. The only closely related transition metal complex bearing a cyclopentadienyl ring, carbonyls and trimethylaniline is [Cp(CO)2Mn{NH}] which was obtained at temperatures below 0 C by reacting the complex [Cp(CO)2Mn(THF)] with 2,4,6-trimethylaniline
