The synthesis and characterization of Zinc(II), Mercury(II), and Iron(III) complexes have garnered significant interest due to their diverse applications in fields such as catalysis, medicine, and materials science. This study focuses on the preparation of these metal complexes using various ligands, particularly Schiff bases, which exhibit chelating properties that enhance metal coordination. The complexes are synthesized through direct reaction methods involving metal salts and ligands in suitable solvents, followed by purification techniques such as recrystallization. Characterization of the synthesized complexes is achieved through an array of analytical techniques. UV-Visible spectroscopy provides insights into the electronic transitions and ligand field interactions, while Infrared (IR) spectroscopy elucidates the coordination modes by identifying shifts in functional group vibrations. Nuclear Magnetic Resonance (NMR) spectroscopy reveals the electronic environments of the ligands in the complexes, enhancing our understanding of their structure. Furthermore, Single-Crystal X-ray Diffraction (SCXRD) is employed to ascertain the three-dimensional arrangements of atoms, confirming the geometries and bonding environments of the complexes. The thermal stability of the complexes is evaluated using Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC), providing essential data on their thermal behavior. Additionally, Mass Spectrometry and Cyclic Voltammetry (CV) are utilized to determine molecular weights and investigate electrochemical properties, respectively. The applications of Zinc(II), Mercury(II), and Iron(III) complexes are diverse. Zinc complexes demonstrate antimicrobial properties, making them suitable for medical applications, while Mercury complexes are explored for their catalytic abilities. Iron(III) complexes are significant in various biochemical processes and serve as potential therapeutic agents. This review provides a comprehensive overview of the synthesis, structural characterization, and application potential of Zinc(II), Mercury(II), and Iron(III) complexes. By shedding light on their properties and versatile applications, this study underscores the potential of these complexes in the development of new functional materials and therapeutic agents, paving the way for future innovations in materials science and medicinal chemistry.
