| Abstract: The mono- and di- substituted derivatives of the parent cluster {μ3-H(Ph)C=C}FeCo2(CO)9 (1) have been synthesized by facile substitution reactions. The compound {μ3-H(Ph)C=C}FeCo2(CO)7(dppe) (2)， {μ3-H(Ph)C=C}FeCo2(CO)8(PPh3) (3) and {μ3-H(Ph)C=C}FeCo2(CO)8(AsPh3) (4) were characterized by elemental analysis， IR， 1H ，31P NMR， MS and X-ray crystallography. The new cluster 2 crystallizes in monoclinic space group P21/n， with a=0. 8614(5)nm， b=1.6404(8)nm， c=2.6574(14)nm， β=96.3222(12)°， V=3.732(3)nm3， Z=4， S=0.886， Δρmax=0.335e·nm-3， Δρmin=-0.379e·nm-3. Final R indices [I >2σ(I)]： R1=0.0432， wR2=0.0695. CCDC： 164600. | |||||||||||||||||
