Organometallic Compounds Synthesis and Characterization

Dichlorobis(indenyl)-titanium(IV) and -zirconium(IV), (C9H7)2TiCl2 and (C9H7)2ZrCl2, react with bidentate Schiff bases such as salicylidene aniline, salicylidene-o-toluidine, salicylidene-m-toluidine and salicylidene-p-toluidine in a 1:1 molar ratio in refluxing tetrahydrofuran in the presence of triethylamine to yield complexes of the type (C9H7)2Ti(SB)Cl and (C9H7)2Zr(SB)Cl, respectively where SB is the anion of the corresponding Schiff base, SBH. The new derivatives have been characterised on the basis of their elemental analyses, conductance measurements and spectral (IR, 1H NMR and electronic) studies.
