The Co²⁺ and Ni²⁺ complexes of H₂L ligand were isolated. By using a variety of methods, including elemental (CHN) analysis, FT-IR, UV-visible, and NMR spectroscopy, the assembly of the ligand and its chelates was completely clarified. Additionally, measurements of magnetic field strength and molar conductance were made. Thermal measurements using TG and DTG were made. Horowitz and Coats equations were used to discuss the complex's thermodynamic and kinetic properties. Finally, the compound under test had its biological activity assessed.
