The reaction of octacarbonyldicobalt and dipropargyl malonateafforded the two expected compounds [CH2(CO2CH2C2H-μ)2][Co2(CO)6]2 1 and [HC2CH2O(O)C～CH2CO2CH2C2H-μ][Co2(CO)6)] 2. Both 1 and 2 were characterized by elemental analysis, IR and NMR. The molecular structure of 1 was determined by single-crystal X-ray diffraction. The crystal belongs to the triclinic system, space group P with the following crystallographic parameters～: a=7.7492(15), b=12.925(3), c=14.366(3) Å, α=81.92(3), β=77.94(3), γ=89.48(3)°, V=1392.9(5)Å3, Z= 2, Mr=751.99, Dc=1.793 g/cm3, F(000)=740, μ(Mo-Kα)=24.13 cm-1 and final R=0.0880 for 5421 observations with I>2σ(I).
