The triply Mo-Mo bonded molecule [Cp(CO)2Mo]2 was reacted with the cyclic sulfides S(CH2)n (n = 4-6). The species Cp(CO)2Mo(μ-S(CH2)n)Mo(CO)2Cp were isolated and characterized by their analytical and spectroscopic data. X-Ray structure analysis of the compound Cp(CO)2Mo(μ-S(CH2)6)Mo(CO)2Cp proved the cyclic sulfide to act as a bridging ligand
