The title compound, [Fe(C7H11)(CO)3]BF4, has been found to exist in the expected piano-stool geometry, except that the unique carbonyl ligand is tilted towards the dienyl ligand by about 25° relative to the other carbonyl ligands. As in the case of the [Co(C5H5)(C7H11)]+ cation, a large difference appears to exist between the internal C—C—C bond angles [129.1 (7) versus 122.1 (6)°] of the open dienyl ligand.
