Title: High-nuclearity clusters containing carbene ligands. Synthesis, structural analyses, and isomerization of disulfidohexaosmium carbonyl cluster compounds containing secondary (dimethylamino) carbene ligands

The trimethylamine complex Os/sub 3/ (CO)/sub 8/(NMe/sub 3/)(..mu../sub 3/-SC/sub 6/H/sub 4/)(..mu..-H/sub 2/) (1) was prepared as a mixture of two slowly interconverting isomers. Refluxing 1 in a heptane solution yielded a mixture of three new hexaosmium clusters that are all isomers with the formula Os/sub 6/(CO)/sub 16/(C(H)NMe/sub 2/)(..mu../sub 3/-S)(..mu..-H)/sub 2/. This reaction represents another example of the arene elimination/cluster condensation sequence that was observed and previously reported for Os/sub 3/(CO)/sub 10/(..mu..-SPh)(..mu..-H). 18 references, 2 figures.
