Question

$\mathrm{H}_{2} \mathrm{Os}_{3}(\mathrm{CO})_{10}(25.35)$ catalyses the isomerization of alkenes: $\mathrm{RCH}_{2} \mathrm{CH}=\mathrm{CH}_{2} \rightarrow E-\mathrm{RCH}=\mathrm{CHMe}+Z-\mathrm{RCH}=\mathrm{CHMe}$ (a) By determining the cluster valence electron count for $\mathrm{H}_{2} \mathrm{Os}_{3}(\mathrm{CO})_{10}$ deduce what makes this cluster an effective catalyst. (b) Propose a catalytic cycle that accounts for the formation of the products shown.
