摘要: A triple-decker complex of tungsten, [(Cp*W)2{μ-η6:η6-B4H4Co2(CO)5}(H)2] (1; Cp* = η5-C5Me5), with a planar middle deck has been isolated by thermolysis an in situ formed intermediate from the reaction Cp*WCl4 and LiBH4 Co2(CO)8. In addition, we have also another complex, [(Cp*W)2{μ-η6:η6-B5H5Fe(CO)3}(H)2] (4), having puckered central ring, similar Fe2(CO)9. Clusters 1 4 are unprecedented examples 24-valence electron bridging hydrogen atoms.
