In the title compound, [Fe(C₂₅H₂₄O₂P)(C₁₈H₁₅P)(CO)₂]PF₆, the Fe atom adopts a square-based pyramidal coordination geometry with the carbonyl groups and the two C=C bonds of the diene defining the basal sites and the phosphane ligand the apical position. The diene ligand has an E,E geometry, with the phospho­nium fragment pointed away from the Fe atom. The crystal structure displays C—H⋯F and C—H⋯O hydrogen bonding. The PF₆⁻ anion is rotationally disordered over four orientations.
