New Schiff base derivatives of heterometallic-μ-oxoisopropoxide [Bu2SnO2AlB(OPri)4] have been synthesized by the thermal condensation μ-oxoisopropoxide compound with Schiff bases in different molar ratios (1:1-1:2) yielded the compounds of the type [Bu2SnO2AlB(OPri)4-n(SB)n] (where n is 1-2 and SB = Schiff base anion) respectively. The μ-oxoisopropoxide derivatives have been characterized by elemental, spectral (IR, 1H, 13C, 27Al, 119Sn and 11B NMR), and molecular weight measurement. The studies reveal that the derivative compounds show dimeric nature. Further these are found low susceptible to hydrolysis as compared to parent compound and may prove excellent precursors for the mixed metal oxides.
