N,N′-Bis(trimethylsilyl)benzamidinato complexes of vanadium(V), niobium(V) and tantalum( V) have been prepared starting from tBuN=MCl3 · n py and tBuN=MCpCl2, respectively: tBuN=V[PhC(NSiMe3)2] nCl3-n (n = 1, 2); tBuN=M[RC(NSiMe3)2]Cl · py [M = Nb. Ta; R = C6H5, C6H4(4-CF3)]; tBuN=MCp[RC(NSiMe3)2]Cl [M = V. Nb, Ta; R = C6H5, C6H4- (4-CF3)]; tBuN=VCp[PhC(NSiMe3)2](OtBu). The syntheses of silylated tert-butylamido complexes tBuN=M[NtBu-SiMe2-NHtBu]Cl2 · py (M = Nb, Ta), tBuN=V[NtBu-SiMe2-OtBu]Cl2 and tBuN=M[NtBu-SiMe2-OtBu]Cl2 · py [M = Nb, Ta (20)] are also described. The compounds have been investigated by 1H NMR data,51V NMR data, mass spectra. X-ray data diffraction analysis.
