Binuclear WFe complexes containing a phosphaallyl bridge can be synthesized from W(CO)₅-stabilized vinylphosphanes such as 1 (R  H) by reaction with the Fe₂ complex 2. In the product 3, the bridging ligand functions simultaneously as a 2e and 3e donor. The structure was elucidated by X-ray diffraction analysis.

6 Suitable single crystals of 5 and 7 were obtained by slow evaporation of CH₂Cl₂ solutions at room temperature. Data were collected at −100°C using Mo_κα radiation for 5 and Cu_κα radiation for 7 (Philips PW 1100/16 automatic diffractometer). Both crystal structures were solved by the heavy atom method using the Enraf-Nonius SDP package. Hydrogen atoms were introduced at their computed positions but not refined.– 5: orthorhombic, space group P2₁2₁2₁, a = 17.278(6), b = 16.277(6), c = 6.956(3) Å, α = β = γ = 90°, V = 1956 Å³, Z = 4, ρ_calc = 2.06 g cm⁻³, F(000) = 1160, 1390 observed reflections, R₁ = 0.048, R₂ = 0.078. Unfortunately, the single crystals of 5 are highly mosaic; the quality of this data set is therefore very poor and only the overall geometry of 5 is meaningful.– 7: triclinic, space group P1, a = 10.724(4), b = 12.424(4), c = 10.647(4) Å, α = 97.53(2), β = 117.86(2), γ = 72.48(2)°, V = 1196 Å³, Z = 2, ρ_calc = 1.899 g cm⁻³, F(000) = 660, 2931 observed reflections, R₁ = 0.027, R₂ = 0.047.

8 A similar phenomenon has already been noted with phosphirane complexes with a W(CO)₅ group coordinated to the P atom. The protons located on the ring are coupled to P when they are cis to W and not coupled when they are trans, see: A. Marinetti, F. Mathey, Organometallics 3 (1984) 456.
