Abstract

The heterobimetallic-μ-oxoisopropoxide [CaO₂Sn₂(OPrⁱ)₆] provides different salicylate derivatives of the type [CaO₂(Sn₂((OPri)_6-n(RSAL)_n] (where n is 1-4 and RSAL = Salicylate anion) with methyl salicylate (HRSAL¹), ethyl salicylate (HRSAL²) and phenyl salicylate (HRSAL³). The derivatives have been characterized by elemental, spectral (IR, ¹H, ¹³C NMR), thermal and molecular weight measurement. The hydrolyzed product of these salicylate derivatives obtained by hydrothermally assisted sol-gel process favors the formation of multicomponent oxides subject to their thermal study. The studies reveal that salicylate derivatives are monomeric in nature and low susceptible to hydrolysis in comparison to parent compound and may prove excellent precursors for the mixed metal oxides.
