The novel tetrahedral clusters (μ3-CR)Co2M(CO)8(η5-Ind) (M=Mo,W; R=H, CH3, C6H5, COOC2H5) 5–12 containing the indenyl ligand were isolated from reactions of tricobalt clusters (μ3-CR)Co3(CO)9 (R=H, CH3, C6H5, COOC2H5) and K(η5-Ind)M(CO)3 (M=Mo,W) under mild conditions. The cluster complex (μ3-CC6H5)CoMo2(CO)7(η5-Ind)(η5-Cp (Cp*=C5H4C(O)CH3) 16 was obtained via the stepwise metal exchange reaction of
