Dicyclopentadienyl-niobium(III) and dicyclopentadienyl-niobium(IV) complexes
The reduction of (η-C5H5)2NbCl2 (I) under various conditions gives the dimer (η-C5H5)4Nb2Cl3 (II) containing niobium(III) and niobium(IV). Reaction of II with AgClO4 gives [(η-C5H5)4Nb2Cl2]+ ClO4- (III). FeCl3 and (C6F5)2 TlBr displace I from II to give (η-C5H5)2Nb(μ-Cl)(μ-X)MY2, where MFe, XYCl(...

| Sumario: | The reduction of (η-C5H5)2NbCl2 (I) under various conditions gives the dimer (η-C5H5)4Nb2Cl3 (II) containing niobium(III) and niobium(IV). Reaction of II with AgClO4 gives [(η-C5H5)4Nb2Cl2]+ ClO4- (III). FeCl3 and (C6F5)2 TlBr displace I from II to give (η-C5H5)2Nb(μ-Cl)(μ-X)MY2, where MFe, XYCl(IV) and MTl, XBr, YC6F5 (V). Reactions of I with metal halides MXY2 give (η-C5H5)2ClNb(μ-Cl)MXY2 where XYCl, MAl (VI), Fe (VII), Tl (VIII) and XBr, YC6F5, MTl (IX). The chemical behaviour of all these compounds is described. |
