Dicyclopentadienyl derivatives of niobium(IV) containing two different cyclopentadienyl ligands have been synthesized.The products obtained are characterised by mass and EPR spectroscopy and by elemental analysis.Starting from NbCl5, unequivocal selective routes proceed via monocyclopentadienyl complexes.The possibility of selectivity obtaining several (RCp)NbCl4 compounds from RC5H4SnBu3 and a heptane suspension of NbCl5 is presented.Evidence is given for formation of a monocyclopentadienyltrichloroniobium(IV) moiety either by reduction of (RCp)NbCl4 with aluminium or stannous chloride in acetonitrile or by monosubstitution of niobium tetrachloride with RC5H4SnBu3.
