Synthesis and X -Ray Crystal Structure of the Heterobimetallic Complex [FeRh (μ-CO)(CO)3((μ-PBut2)((μ-Ph2PCH2PPh2)]

The reaction of the phosphido-bridged metal carbonyl [FeRh(CO) (μ-PBu )] (1) with dppm [dppm = bis(diphenylphosphino)methane] leads to the heterobimetallic complex [FeRh(μ-CO)(CO) (μ-PBu )(μ-dppm)] (2) in good yields. The molecular structure of 2 was determined at room temperature [triclinic, space...

More Information
Summary:The reaction of the phosphido-bridged metal carbonyl [FeRh(CO) (μ-PBu )] (1) with dppm [dppm = bis(diphenylphosphino)methane] leads to the heterobimetallic complex [FeRh(μ-CO)(CO) (μ-PBu )(μ-dppm)] (2) in good yields. The molecular structure of 2 was determined at room temperature [triclinic, space group P1̄, a = 9.509(6), b = 13.637(5), c = 14.926(8) Å, α = 81.38(4), β = 82.75(4), γ = 71.25(4)°]. The compound acts as a homogeneous catalyst precursor in the hydroformylation reaction of ethylene, but it decomposes during this process.
