| 摘 要： | The treatment of dipropargyl ether HC2CH2OCH2C2H with Co2(CO)8 resulted in the formation of a novel cluster Co2(CO)6]μ-HC2CH2OCH2C2H-μ]Co2(CO)6]. The cluster was characterized by C/H analyses, IR and 1H NMR spectroscopy and X-ray crystal structure determination. It belongs to monoclinic system, space group P21/c with the following crystallographic parameters: a=18.149(2), b=7.0111(7), c=20.897(2)(A), β=115.318(7)°, V=2403.7(5)(A)3, Z=4, Mr=665.97, Dc=1.840 g·cm-3, F(000)=1304.00, μ(Mo-Kα)=27.76 cm-1 and R=0.030 for 2372 observed reflections.
