Thermal decomposition study on mixed ligand thymine complexes of divalent nickel(II) with dianions of some dicarboxylic acids

Thermal Degradation Behaviour of Ni(II) Complex of 3,4‐Methylenedioxaphenylaminoglyoxime

“…High activation energy values were calculated at the appropriate linear regions of the temperature range by using five methods and were given in Table 2. The high values indicate that the ligand is strongly bonded to the Ni(II) ions [25]. The activation energy is obtained at nearly the same value for three steps because of the structures of the evolved moieties.…”

“…The negative values of Δ are due to low values and account for the nonspontaneous nature of the reaction [26]. The nonspontaneous nature of the degradation reactions of the complex was supported by the positive value of Δ in the degradation steps [25]. The enthalpy was found to be positive value, and it was partially decreased with increase in temperature.…”

Structural and bio-catalytic aspects of nano crystallite iron(iii) complexes containing triazole-based ligands

“…37 This interpretation is consistent with the positive sign of the calculated Δ G * values for the three successive pyrolysis steps of the present iron( iii ) complexes. 38 In the same respect, the calculated values of Δ H * corresponding to those of Δ S * and Δ G * (Table 3) excluded the exothermic behavior of the studied pyrolysis reactions. 38…”
