Notes: New Cyclooctatetraene Complexes of Niobium[1]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-η3- and a supine-η4-COT ligand which interchange their role at elevated temperature. That of 5 shows a supine η3-COT ligand.
