Syntheses and spectroscopic studies of mono- and dicyclopentadienyl titanium (IV)/zirconium (IV) derivatives with S-alkyl-β-N-(acetylferrocenyl) methylene dithiocarbazates

Abstract

The reactions of dicyclopentadienyl titanium (IV)/ zirconium (IV) dichloride and monocyclopentadienyl titanium (IV) trichloride with thio-Schiff bases (LH), derived by the condensation of S-methyl/ethyl/propyl dithiocarbazic acid and acetylferrocene, have been carried out under inert atmosphere and anhydrous conditions in different stoichiometric ratios. Complexes of the types Cp₂M(L)Cl, CpM(L)₂Cl (M = Ti(IV) or Zr-(IV)), CpTi(L)CI₂, CpTi(L)₂Cl are synthesized and characterized by elemental analysis, electrical conductance, magnetic moment and spectral (electronic, infrared, ¹H NMR) data.
