Kinetic analysis of non-isothermal decomposition of Fe2+, Co2+, Ni2+ and Cu2+ succinate complexes in a nitrogen atmosphere

Isothermal and Nonisothermal Reaction Kinetics in Solids: In Search of Ways toward Consensus

“…In many cases, this extra flexibility in the fitting procedure allows errors in the functional form of the reaction model to be concealed by making compensating errors in the Arrhenius parameters, sometimes by as much as 1 order of magnitude. ,− Because the experiments are typically carried out over a relatively narrow range of temperatures, this kinetic compensation effect usually prevents a reliable determination of the Arrhenius parameters and reaction model from nonisothermal data using the model fitting method . A review 16 has highlighted some of the more spectacular failures of the model fitting method as applied to nonisothermal experimental data. − These problems have led some researchers to mistrust kinetic results of nonisothermal experiments in general; however, in our view this attitude is justifiable only as it pertains to the use of the model fitting method. Given a proper kinetic treatment, nonisothermal experiments are unquestionably capable of producing reliable kinetic information …”

[40][41][42][43][44][45] These problems have led some researchers to mistrust kinetic results of nonisothermal experiments in general; 46 however, in our view this attitude is justifiable only as it pertains to the use of the model fitting method. Given a proper kinetic treatment, nonisothermal experiments are unquestionably capable of producing reliable kinetic information.…”

Role of carboxylate ion and metal oxidation state on the morphology and magnetic properties of nanostructured metal carboxylates and their decomposition products

“…Note that in case of bulk cobalt succinate, a dimeric structure is known where the carboxylate group is bonded to two different cobalt atoms to give a tetrahedral environment. 3 This structural necessity probably leads to shorter rods. Thus it seems that the bidentate succinate ion also favours the formation of rods like the oxalate ion only if the metal ion is in +2 oxidation state as evidenced from the formation of cobalt succinate nanorods.…”

“…Several studies on single crystals of three-dimensional open framework structures complexed with metal ions obtained by hydrothermal method have been reported. 1,2 Kinetic analysis on the thermal decomposition of transition metal succinates obtained by coprecipitation method has also been reported, 3 which led to either single crystalline (0⋅01 mm) or micronsized polycrystalline materials. We have been interested in the nanostructures of metal-organic-based systems.…”

Mixed-Ligand Metal Succinate Complexes with 1,10-Phenanthroline and Ethylenediamine: Synthesis, Characterization, Spectroscopic and Thermal Studies. Crystal Structure of Succinatocobalt(II) Complex with Phenanthroline

“…Spectral and thermal properties of divalent transition metal complexes of suc were studied by a number of researchers [8][9][10][11]. It was shown that suc formed stable compounds with Fe(II), Co(II), Ni(II), Cu(II), Zn(II) and Cd(II), whereas anionic complexes of Cu(II) such as K 2 [Cu(C 4 H 4 O 4 ) 2 ] and K 4 [Cu(C 4 H 4 O 4 ) 3 ] Á 2H 2 O were found to be very unstable.…”
