Abstract

Techniques such as elemental analysis, magnetic moment, molar conductance, UV-Vis, and FT-IR were used to characterize the recently synthesized diphenyl glycolic acid-Leucine ligand and its Cr (III), Ni (II), and Cu (II) complexes. Thermal analysis was used to determine the thermal stability and decomposition pattern of the Cr (III), Ni (II), and Cu (II) complexes. The TG curves were used to compute kinetic parameters such as activation energy (ΔE), frequency factor (A), entropy of activation (Δs), and order parameter (n) using the Coats Redfern and Horowitz Metzger equations. Nine mechanistic equations have been used to examine the reaction mechanism by employing non-isothermal approaches. The end products are discovered to be their corresponding oxides, and [CrBL(H2O)2(CH3COO)2] < [CuBL(H2O)2(CH3COO)2] < [Ni(BL)2(H2O)2] is the sequence in which they are most stable. The Cr (III) and Cu (II) complexes exhibit two-stage decomposition pattern in their TG curve whereas Ni (II) complex shows a three-stage decomposition pattern.
