摘要：

The (butadiene)niobium complexes Cp'Nb(C4H6)2 and Cp'Nb-(C4H6)(PMe3)2 (Cp' = C5H4Me) react with cyclooctatetraene (COT) to give Cp'Nb(C4H6)(COT) (2), Cp'Nb(COT)2 (3), and Cp'Nb(PMe3)2(COT) (5) with fluxional COT ligands. The structure of 3 exhibits a prone-eta(3)- and a supine-eta(4)-COT ligand which interchange their role at elevated temperature. That of 5 shows a supine eta(3)-COT ligand.
