This study presents a comprehensive investigation of the physicochemical properties, thermal behaviour, and biological studies of VO(IV), MoO2(VI), and UO2(VI) complexes with a hexadentate tetra anionic ligand. The synthesis of the complexes was carried out using appropriate metal salts and the ligand, followed by characterization using various analytical techniques. Fourier-Transform Infrared (FT-IR) spectroscopy was employed to investigate the functional groups involved in metal-ligand coordination
