The reactive cluster RuCo2(CO)11 was treated with numerous inorganic, organo-element, and organic reagents which are potential precursors of μ3-bridging four electron ligands.Capping could be achieved with Co(CO)4- forming RuCo3(CO)12-, with RPH2 (R=Me, Ph, Tol) forming RuCo2(CO)9PR (3a-c), with MeAsH2 forming RuCo2(CO)9AsMe (4), with H2S, HSEt, or S8 forming RuCo2(CO)9S (5), with Ph2Se2 leading to RuCo2(CO)9Se (6), with TolC=-WCp(CO)2 forming RuCo2W(CTol)Cp(CO)10 (8), and with LnM-C=-CPh (Ln=Cp(CO)2Fe, Cp(CO)2Ru, Cp(CO)3W) forming RuCo2M(C2Ph)(CO)8Ln (9, 10, 12).With tBuC=-P and Cp(CO)2Mo=-MoCp(CO)2 fragmentation products were obtained, tBuNC led to CO substitution.The new tetranuclear clusters RuCo2W(CTol)Cp(CO)10 (8), RuCo2Fe(C2Ph)Cp(CO)10 (9), and RuCo2W(C2Ph)Cp(CO)11 (12) were confirmed by crystal structure analyses.
