The Reaction of BIS (cyclopentadienyl) titanium (IV) dichloride with acetophenone picolinoyl hydrazone (AcPH-H), salicylaldehyde picolinoyl hydrazone (SPH-H2), O-hydroxyacetophenone picolinoyl hydrazone (OPH-H2) have been carried out in anhydrous tetrahydrofuran under stirring in the presence and absence of amine. Two types of complexes are obtained depending upon the pH of the medium. [CpTiL]n and [ Cp2TiCl2L] have been isolated in the presence and absence of amine respectively. They are characterized by elemental analysis, electrical conductance, magnetic moment, and spectral (electronic, IR and 1H.n.m.r) studies. 1H.n.m.r spectra reveal rapid rotation of the cyclopentadienyl ring along the metal ring axis at 25°C.
