Synthesis of Derivatives of Heterobimetallic [Sn(II);Ti(IV)]-µ-oxo-isopropoxide with Schiff Bases

Abstract

With an aim to enhance the stability and volatility of the heterometallic [Sn(II);Ti(IV)]-µ-oxo-isopropoxide a number of substitution reactions of the complex are carried out with different schiff bases viz Salicylidene aniline (HSB1), Salicylidene-o-toluidene (HSB2) and Salicylidene-p-chloroaniline (HSB3) have been performed in different molar ratios in refluxing benzene resulting in to the formation of products of the type [SnO2Ti2(O-i-Pr)5(SB)], [SnO2Ti2(O-i-Pr)4(SB)2], [SnO2Ti2(O-i-Pr)3(SB)3] and [SnO2Ti2(O-i-Pr)2(SB)4]. The schiff base derivatives have been characterized by elemental, liberated isopropanol and spectral analysis (IR, 1H , 13C NMR).
