Cluster expansion reactions which had been applied successfully with cobalt containing reagents could not be used with the corresponding reagents of rhodium and iridium.CpRh(CO)2 and CpIr(CO)2, however, were suitable precursors of CpM building blocks by which trinuclear clusters could be expanded to tetra- (A) and pentanuclear clusters (B).Thus, from μ3-RP-M3 complexes, RP bridged tetranuclear clusters with FeCo2Rh, RuCo2Rh, Fe2CoRh, Ru2CoRh, FeRuCoRh, RuCoWRh, RuCo2Ir, and FeRuCoIr frameworks and pentanuclear clusters with FeCo2Rh2, RuCo2Rh2, Fe2CoRh2, Ru2CoRh2, and FeRuCoRh2 frameworks were formed.Analogously, with CpCo(CO)2 a RPFeCo4 cluster and from (μ3-S)RuCo2(CO)9 a SRuCo2Rh2 cluster was obtained.As a rule the new clusters resulted in the form of several isomers.Crystal structure determinations have revealed unusual bonding situations for the tetranuclear clusters RhPRuCo2RhCp(CO)10 (11) and MePFeRuCoIrHCp(CO)10 (17α).For the pentanuclear clusters they have confirmed the octahedral PM5 heavy atom framework as exemplified by MePFeRuCoRh2HCp2(CO)8 (27β).
