Synthesis and Characterization of Schiff Bases Derivatives of Heterotrimetallic [Al(III); Sn(II); Ti(IV)]-µ-oxoisopropoxide-µ-oxon-propoxide [SnO2TiAl(OPri )2(OPrn )3]

Abstract

Tin diacetate and aluminium isopropoxide in equimolar proportion in xylene affords the complex [(OAc)SnOAl(OPri )2] which on reaction with Ti(OPrn )4 in 1:1 molar ratio yielded a new organoheterotrimetallic-μ-oxoisopropoxide-μ-oxon-propoxide [SnO2TiAl(OPri )2(OPrn )3] with continuous liberation of isopropyl acetate and propyl acetate formed during the course of reaction. The preparation of Schiff base complexes of the compound [SnO2TiAl(OPri )2(OPrn )3] was carried out in refluxing benzene by the reaction of µ- oxomixedpropoxide compound in different molar ratios (1:1 and 1:2) with Schiff bases (1-(2- Pyridyl) ethanonehydrazine carboxamide (HSB1 ) and 1-Furanyl) ethanonehydrazin carboxamide (HSB2 ). The complexes were characterized by spectral analysis (IR, 1H, 13C, 119Sn, 27Al NMR and mass spectra). The spectral studies confirmed that the proposed framework of the new organoheterotrimetallic complexes and indicated a tetrahedral geometry around the central metal atom.
