Reactivities governed by a single metal atom M in mixed-metal highnuclearity clusters having [Ru5M(C)] core (MÂ =Â Co, Rh, Pd): Site-nonselective, site-selective, and chemo-selective variations in the SO2-trapping reactions

Depending on the kind of M in mixed-metal carbonyl clusters with [Ru5M(C)] core, the attacking SO2 behaves in totally different way, suggesting critical importance of the single hetero atom.
