The reactions of bis(2-mercaptoethyl) sulfide or bis(2-mercaptoethyl) ether with [Co2(µ-HOCH2CCCH2OH)(CO)6] in the presence of HBF4·OEt2 afford [Co2µ-C2(CH2SCH2CH2)2X}(CO)6](X = S or O) respectively together with dimeric products. The structure of the monomer [Co2µ-C2(CH2SCH2CH2)2S}-(CO)6] has been established by X-ray crystallography and comprises a hexacarbonyldicobalt unit transversely bridged
