Tin diacetate and aluminium isopropoxide in equimolar proportion in xylene affords the complex [(OAc)SnOAl(OPr i ) 2 ] which on reaction with Ti(OPr n ) 4 in 1:1 molar ratio yielded a new organoheterotrimetallic-μ-oxoisopropoxide-μ-oxon-propoxide [SnO 2 TiAl(OPr i ) 2 (OPr n ) 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 [SnO 2 TiAl(OPr i ) 2 (OPr n ) 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 (HSB 1 ) and 1-Furanyl) ethanonehydrazin carboxamide (HSB 2 ). The complexes were characterized by spectral analysis (IR, 1 H, 13 C, 119 Sn, 27 Al 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.
