摘　　要：The reaction of μ alkyne bridged dimolybdenum compound 〔Mo 2( μ C 2HPh)(CO) 4( η 5 C 5H 4C(O)Me) 2〕 1 with Co 2(CO) 8 in refluxing toluene gave a new butterfly compound 〔Co 2Mo 2( μ 4 C 2HPh)( μ CO) 4(CO) 4( η 5 C 5H 4C(O)Me) 2〕 2 which was fully characterized by elemental analysis, IR, 1H NMR and X ray single crystal diffraction techniques. 2 crystallized in monoclinic system, C 30 H 20 Co 2Mo 2O 10 , M r =850.23, space group P2 1/a(#14), a=14.165(5), b=12.498(2), c=16.204(2) , β = 96 50(2)°, V = 2850(1) 3, Z = 4, D c = 1.981 g cm -3 , F(000)=1672, μ (Mo Kα )=20.41 cm -1 , final R=0.030, R w =0.039 for 4831 observable reflections with I>2σ(I ). The structure contains a Co 2Mo 2 butterfly core, and each Mo-Co bond is spanned by an asymmetric semi bridging carbonyl ligand.
