N2 - The reactions of [H2Os3(CO)10] with hetero-cyclohexanes with positions 1, 3 and 5 substituted by nitrogen or sulfur atoms; 1,3,5-trimethyl-1,3,5-triazinane, 3,5-dimethyl-1,3,5-thiadiazinane, 5-methyl-1,3,5-dithiazinane and 1,3,5-trithiane; produce compounds where sulfur atoms and NCN fragments bridge metal-metal bonds as well as complexes containing trinuclear metal fragments linked by SCS and SCNCS units. 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 for the non-coordinated ligands.
