摘要：
The tetrahedral metal-cluster complexes containing alkylcyclopentadienyl ligand η5-RC5H4(CO)2 MCo3(CO)6(μ-CO)3(M = Mo, W; R=CH3, C2H5, n-C4H9, C6H5CH2) have been synthesized by thermal reaction of metal-metal single-bonded compounds [η5-RC5H4(CO)3M]2 with Co2(CO)8, and characterized by elemental analysis, 1R, 1H NMR and MS spectroscopies. The thermal reaction mechanism is studied and a single-crystal molecular structure of η5-n-C4H9C5H4(CO)2MoCo3(CO)6(μ-CO)3 determined with the X-ray diffraction method. The molecule crystallizes in the space group P21/C with cell parameters a= 1.0088(2), b= 1.3063(3), c=1 8320(5) ran, β = 96.04(2)°; the final deviation factor R = 0.041.
