Abstract
5-methoxy-5,6-bis(3-nitrophenyl)-4,5-dihydro-1,2,4-triazine-3(2H)-thione (NBTS) and its Ni(II), Co(II) and Cu(II) metal complexes have been synthesized and their structure elucidated by elemental analysis, conductivity measurements, UV-Visible, FT-IR, 1H-NMR,LC-Mass and thermal analysis. The complexes are soluble in almost all organic solvents and are non-electrolytes. Thermal analysis are investigated and showed either two or three thermal decomposition steps. Kinetic parameters such as Ea, ΔH, ΔS and ΔGof the thermal decomposition stages have been evaluated using Broido’s method. The antibacterialand antioxidantactivity of the uncoordinated ligand and its metal complexes have been studied.The results indicate that the complexes are more potent when compared to the ligand.
