A new heterobimetallic-µ-oxoisopropoxide of the type [SnO2 Ti2(i-OPr)6] has been synthesized by the thermal condensation of tin diacetate and titanium isopropoxide in 1 : 2 molar ratio in refluxing xylene. The isopropoxy substitution reactions of this µ-oxoisopropoxide compound with β-diketones in different molar ratios (1 : 1·1 : 4) gives compounds of the type [SnO2Ti2(i-OPr)6-nLn ] (where n is 1-4 and L = acetylacetonate/benzoylacetonate anion). The µ-oxoisopropoxide compound has been characterized by elemental, spectral analysis (IR, 1H , 13C, 119Sn NMR and mass) and molecular weight measurement. The β-diketonates of [SnO2 Ti2(i-OPr)6] have been characterized by elemental, liberated isopropanol and spectral analysis (IR, 1H, 13C NMR).
