Dichloro bis(cyclopentadienyl)zirconium(IV), Cp2ZrCl2, reacts with bidentate Schiff bases such as salicylidene-4-anisidine, salicylidene-4-phenetidine, salicylidene-4-chloroaniline, salicylidene-4-bromoaniline, salicylidene-4-iodoaniline and salicylidene-4-nitroaniline in a 1:1 molar ratio in refluxing tetrahydrofuran in the presence of triethylamine to yield Cp2Zr(SB)Cl, where (SB)- is the anion of the corresponding Schiff base, SBH.The new derivatives have been characterized on the basis of elemental analysis, molecular weight determination, conductance measurement and spectral (IR, 1H NMR) and electronic studies.

, p. 907 - 914 (2007/10/02)
A series of (C9H7)2Zr(SB)Cl complexes where SB(-) is the anion of bidentate Schiff base derived from salicylaldehyde and 4-substituted anilines, viz. salicylidene-4-anisidine, salicylidene-4-phenetidine, salicylidene-4-chloroaniline, salicylidene-4-bromoaniline, salicylidine-4-iodoaniline and salicylidine-4-nitroaniline, have been synthesized by the reaction of bis(indenyl)zirconium(IV)dichloride and Schiff base (SBH) in 1:1 molar ratio in refluxing THF in the presence of triethylamine.The new derivatives have been characterized on the basis of their elemental analyses, conductance measurements and spectral (IR, 1H-NMR, UV-VIS) studies. - keywords: Bis(indenyl)zirconium(IV) complexes; Schiff base; Conductance; IR; 1H-NMR; UV-VIS
