Abstract

The new heterobimetallic bridging acetyl complex Cp(CO)Fe(μ-C(O)CH₃)μ-PPh₂)Mn(CO)₄ (1) has been prepared by the reaction of CH₃Mn(CO)₅ with PPh₂FeCp(CO)₂ been refined to R = 0.044 and R_w = 0.042 for the 3353 reflections with I > 3σ(I). The acetyl ligand bridges the Fe and Mn centers with the acetyl carbon attached to Fe and the oxygen bound to Mn. The nonbonded metals (Fe. Mn = 3.718 Å) are also bridged by the μ-PPh₂ ligand. The chemistry of complex 1 has been examined with HBF₄, [{CH₃)₃O]BF₄, [Ph₃C]BF₄, H₂, PPh₂Me, and MeLi, and these reactions are discussed. Reaction of HMn(CO)₅ with PPh₂FeCp(CO)₂ gives the bridging hydride complex Cp(CO)Fe(μ-H)(μ-PPh₂)Mn(CO)₄ (3), which has also been structurally characterized. It crystallizes in the monoclinic space group P2_l/n with a = 10.795 (4) Å, b = 13.931 (2) Å, c = 14.497 (4) Å, β = 102.08 (3)°, V = 2132 (2) Å³, and Z = 4. The structure has been refined for the 2412 reflections with I > 2σ(I) to R = 0.057 and R_w = 0.063. The Fe and Mn atoms are separated by 2.806 (1) Å and are bridged by the hydride and the μ- PPh₂ ligand. The Fe atom is further coordinated by the Cp ligand and one CO, and Mn has four additional CO ligands.
