Bis(2,4-pentanedionato)zirconium(IV) aryloxides with the composition ZrCl2-n(acac)2(OAr-X)n (where n = 1 or 2; acac = 2,4-pentanedionato anion; OAr-X = OC6H3Cl 2;-2,6; OC6H3Cl2-2,4 and OC 6H2Cl3·2,4,6) have been synthesized by reacting ZrCl2(acac)2 and Me3SiOAr-X in predetermined molar ratios in toluene under reflux. These complexes have been characterized by physico-chemical techniques such as elemental analysis, IR, 1H NMR, TGA/DTA, molecular weight determinations and molar conductance measurements. The mechanism and kinetic parameters (ΔE* and A) of non-isothermal decomposition have been evaluated from TG curves of the complexes using Coats-Redfern equation. A considerable decrease in the FDTs of the complexes in the TG curves indicate then potential use as precursors in making thin films of ZrO2.
