“…The thermal decomposition of Schiff base derivatives of [CaO 2 Ti(OPr i ) 4 ] have been examined by thermogravimetric analysis under a flow of dry nitrogen, up to 800 o C at a heating rate of 10 ºC/min. The minor weight loss (1.32-1.48 %) starts at 57.5-59.3 ºC and completed at 185-187 ºC with a weight loss of due to presence of moisture and fraction of solvent present, if any.…”

“…The control of particle size and the morphology of the oxide are of crucial importance nowadays both from the fundamental and industrial point of view 2 . The mixed metal oxides prepared from heterometallic-µ-oxoalkoxides [3][4][5][6] have been used for absorbing harmful chemicals 7 and gases such as SO 2, CCl 4 and decontaminating chemical warfare agents 8 . The alkaline earth metal titanates like barium titanate, calcium titanate (CaTiO 3 ), strontium titanate (SrTiO 3 and Ba x Sr 1-x TiO 3 ) due to their exceptional properties expose potential applications in multilayer ceramic capacitors, electro-optic, dielectric and piezoelectric devices [9][10][11][12] .…”

New Schiff base derivatives of heterobimetallic-µ-oxoisopropoxide [CaO 2 Ti 2 (OPr i ) 6 ] have been synthesized by thermal condensation of µ-oxoisopropoxide with salicylidene-aniline (HSB 1 ), salicylidene-o-toluidene (HSB 2 ) and salicylidene-p-chloroaniline (HSB 3 ) in different molar ratios (1:1-1:4) yielded the compounds of the type [CaO 2 Ti 2 (OPr i ) 6-n (SB) n ] (where n is 1-4 and SB = Schiff base anion) respectively. The Schiff base derivatives have been characterized by elemental, spectral (IR, 1 H, 13 C NMR), thermal and molecular weight measurement. Hydrothermally assisted sol-gel process gives the hydrolyzed product and thermal study of these products favors the formation of multicomponent oxides. The studies reveal that Schiff base derivatives are monomeric in nature and low susceptible to hydrolysis as compared to parent compound and may prove excellent precursors for the mixed metal oxides.

1 H, 13 C 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.
