Reaction of an alkyne‐bridged dicobalt complex, [Co 2 (CO) 6 (μ‐Me 3 SiC=Cpy)] 4 , with bis(diphenylphosphino)methylene (DPPM) or bis(diphenylphosphino)ethylene (DPPE) in THF at 55 °C yielded a DPPM or DPPE doubly bridged dicobalt compound, [{μ‐P,P‐PPh 2 CH 2 PPh 2 }Co 2 (CO) 4 (μ‐Me 3 SiC=Cpy)] 5 or [{μ‐P,P‐PPh 2 CH 2 CH 2 PPh 2 }Co 2 (CO) 4 (μ‐Me 3 SiC≡Cpy)] 6 . Compound 5 and 6 were characterized by spectroscopic means as well as X‐ray crystal structure determination.
