Spectroscopic characterization of the products as well as the X-ray crystal structures of complexes [(μ-H)Os3(CO)9(PMe3)]–[μ-(H2CCS2)]–[(μ-H)Os3(CO)10]}, (μ-H)Os3(CO)10(μ-SCH2NMe2)}, [(μ-H)Os3(CO)10]2[μ-S2(CH2)2NMe]} and [Os(S3(CH2)3)2Cl2(CO)2] are reported. A mechanistic proposal for all the reactions is made based in spectroscopic analysis of the reaction mixtures and theoretical calculations
