Abstract Bis(cyclopentadienyl)zirconium(IV) Schiff base derivatives have been synthesized by treating dichlorobis(cyclopentadienyl)zirconium(IV) (Cp2ZrCl2) with bidentate Schiff bases (SBH) viz., N-salicylidenaniline, N-salicylidene-o-toluidine, N-salicylidene-m-toluidine, N-salicylidene-p-toluidine, and N-(2-hydroxyl-1-naphthyliden)aniline, terdentate Schiff bases (SB′H2) viz., N-(3-oxo-1-methylbutyliden)-o-aminophenol and N-(3-oxo-1-phenylbutyliden)-o-aminophenol; quadridentate Schiff base (SB″H2) N,N′-disalicylidene-o-phenylenediamine, in THF, in the presence of triethylamine at room temperature. The resulting derivatives of the type Cp2Zr(SB)Cl, Cp2Zr(SB)2, Cp2Zr(SB′), Cp2Zr(SB″), and (Cp2ZrCl)SB″ [where [SB]−, [SB′]2−, and [SB″]2−-represent the anion of corresponding Schiff bases SBH, SB′H2, and SB″H2] have been characterised by their elemental analysis and by IR, electronic spectra, electrical conductance and molecular weight determinations.
