Abstract:The complexes of chromium and molybdenum with salicylidene-2-aminophenol (shaH2), salicylidene-2-aminoanisole (salanH2), salicylidene-2-aminoaniline (salphenH2) and biquinoline (biq) were studied using the thermogravimetric techniques. The thermal decomposition of all complexes was found to be first order reaction and the thermodynamic parameters corresponding to the different decomposition steps were reported. Molybdenum complexes were found to be more thermally stable and the order of stability was [Mo(CO)4(biq)]>[MoO(salphen)]>[MoO2(salphenH)2]>[MoO4(salan)2]>[MoO(sha)]. Similar trend was found for chromium complexes where [Cr(CO)4(biq)]>[Cr(CO)2(salphen)] >[CrO2(CO)2(shaH2)]>[CrO2(CO)2(salan)2].
Keywords:chromium  kinetics of thermal decomposition  molybdenum   Schiff bases   thermogravimetric studies
