摘　　要：The cluster complex (μ4-η2-C2Ph2) Co4 (CO)8 (μ-CO)2 was synthesized by 'one pot' method starting from Co2(CO)8 and PhCCPh in toluene and characterized by single-crystal structure analysis. It crystallizes in the monoclinic space group P21/c with a=9. 149(3). b=11. 732(2), c=23.551 (6) A, β=92. 62(2)°, V=2525 (1), Z=4, Dc= 1. 83 g/cm3,Mr = 694. 07.μ=26.33cm-1,F(000)=1368. The final R= 0. 039, Rω= 0. 047 for 2812 observed independent reflections(I≥3σ(I)). In the molecule, four cobalt atoms form a butterflyshaped metal skeleton and the ligand C2Ph2 is coordinated to cobalt atoms through two σ bonds and a delocalized four- center π-bonding system.The cluster complex (μ4-η2-C2Ph2) Co4 (CO)8 (μ-CO)2 was synthesized by 'one pot' method starting from Co2(CO)8 and PhCCPh in toluene and characterized by single-crystal structure analysis.
