The cation of the title compound, C19H18FeO2P+·BF4 or [Fe(C5H5)(C12H13P)(CO)2]BF4, features a typical half-sandwich-type structure with four ligands roughly giving a tetra­hedral coordination of the Fe ion.

Experimental. Diffraction: A single-crystal of the title compound was mounted on a Stoe four-circle diffractometer equipped with a CCD-detector (Stadi-CCD). For the data collection 21 omega-scans (1.0 °) with different chi, phi and 2theta settings and a detector to crystal distance of 80 mm were performed. Integration procedures using variable and intensity dependant integration masks and integration width of 1.00 ° yielded a data completeness of more than 99.0% up to a Bragg angle of 60° two-theta.

1H NMR (200?MHz, D6-acetone): δ 7.73 (m, 2 H, Ph), 7.57 (m, 3 H, Ph), 7.06 (dq,2JHP = 36.2?Hz, 4JHH = 0.9?Hz, 2 H, α-H), 5.26 (d, 3JHP = 1.9?Hz, 5 H, Cp), 2.25 (dd, 4JHP = 1.6?Hz, 4JHH = 0.9?Hz, 6 H, Me); 31P NMR (81?MHz, D6-acetone): δ = 58.4 (s).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
