SYNTHESES, CHARACTERIZATION AND THERMAL STABILITY STUDY OF NEW Co(II), Cu(II) AND Zn(II) COMPLEXES DEVIATES FROM SCHIFF BASE 4-(DIMETHYLAMINO)BENZALDEHYDE

Schiff base complexes were known for their various applications in different fields, due to their interesting chemical and physical properties. In this work, Bis(4-dimethylamino)bezylidene) ethanebis(thioamide) (DMABT) as Schiff base ligands was prepared via condensation reaction between 4-(dimethyl amino) benzaldehyde and dithioximade Then, the resulted ligand coordinated with central elements Co(II), Cu(II). and Zn(II). The new complexes are known; [Co2(DMABT)], [Cu2(DMABT)] and [Zn2(DMABT)] were successfully characterized through various techniques such as electrochemical conductivity, magnetic susceptibility, infrared spectroscopy, electronic spectrum measurements, and nuclear magnetic resonance spectroscopy of carbon 13 and proton. In addition, both thermal stability and kinetic parameters were investigated to report data of energy activation reaction, enthalpy, entropy, Gibbs free energy reaction constant, and half-life of thermal decomposition. For the previous proposal, a METTLER Toledo module device was carried out the samples at a 10 °C\min rampage, starting at 25 °C up to 600 °C. According to the reported results, the prepared compounds have tetrahedral shapes with high thermal stability and could be suggested to apply in various future industrial application
