摘　　要：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 : R1=0.0432, wR2=0.0695. CCDC: 164600.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.
