The carbyne compound [Br(CO)2(Py)2Mo(≡CC6H5)] (Py=pyridine) (1a) reacts with Co2(CO)8, Fe2(CO)9 and Mn2(CO)10 to give tetrahedral tri-metal cluster compounds Co2Mo(μ3-CC6H5)Br(CO)8(Py)2 (2), Fe2Mo(μ3-CC6H5)Br(CO)9(Py)2 (3) and Mn2Mo(μ3-CC6H5)Br(CO)10(Py)2 (4)respectively.Tri-metal cluster compound Co2Mo(μ3-CC6H5)Br(CO)8(bipy) (bipy=α,α'dipyridyl) (5) is prepared in a similar reaction sequence from [Br(CO)2(bipy)Mo(≡CC6H5)] (1b) and Co2(CO)8. IR,1H and 13C NMR spectral data of these compounds are reported and discussed.The crystal structure of compound (5) has been determined by X-ray diffraction.
