Oxidation of (η5-C5R5)MoH3(dppe) (R = Me, Et) by Cp2Fe+ in wet THF leads to the formation of the corresponding (η5-C5R5)Mo(OH)2(dppe). These compounds show a low-potential reversible oxidation wave. The structure of the C5Et5 complex has been confirmed by X-ray diffraction methods: triclinic; space group P1; a = 11.030(1); b = 12.533(1); c = 16.241 (1) A?; α = 68.585(7); β = 75.197(5); γ = 83.991(7)°; V = 2020.6(3) A?3; Z = 2; Dcalc = 1.324 g cm-3, μ(Mo-Kα) = 0.441 mm-1; R1 = 0.0325; wR2 = 0.0875 for 415 parameters and 6823 independent reflections [Rint = 0.0177] with I = 2σ(I). The molecule shows a four-legged piano-stool geometry with two terminal OH ligands in a relative trans configuration. The complex EPR properties indicate that an equilibrium mixture of various species is present in solution.
